Description

Technical Field

[0001] This utility model relates to the field of motor braking, and in particular to a high-efficiency variable frequency drive motor with an integrated braking unit. Background Technology

[0002] In industrial production, material handling, and automated equipment, variable frequency drive motors are increasingly widely used due to their advantages of precise speed regulation and energy saving. These motors typically require braking devices to meet the needs of rapid equipment shutdown, static locking, and preventing load slippage. Especially in scenarios with high requirements for braking reliability, such as hoisting machinery, elevators, and conveyor lines, the performance of the braking unit directly affects the safety and efficiency of equipment operation.

[0003] In traditional friction braking, the friction pads are prone to creep during long-term static locking, leading to a gradual decrease in braking force. If vibration or external impact occurs, the brake pads and brake disc may slip relative to each other, making it impossible to reliably lock the load. At the same time, the engagement and disengagement response of the mechanical locking structure is slow, and each braking action generates a mechanical impact, which will accelerate component fatigue damage with long-term high-frequency use. For scenarios that require frequent start-stop and rapid deceleration, the pure mechanical locking mechanism cannot meet the timeliness and stability requirements of dynamic braking. Utility Model Content

[0004] The main purpose of this invention is to provide a high-efficiency variable frequency drive motor with an integrated braking unit, which can effectively solve the problem of low reliability of traditional devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency variable frequency drive motor with an integrated braking unit includes a variable frequency motor, a connecting flange fixedly connected to the front of the variable frequency motor, and a braking module fixedly connected to the front of the connecting flange.

[0006] Preferably, a guide disk one and a guide disk two are fixedly connected to the lower part of the top cover, and a rotating seat one and a rotating seat two are fixedly connected to the inner sides of the guide disk one and the guide disk two, respectively. A guide disk three is fixedly connected between the rotating seat one and the rotating seat two.

[0007] Preferably, the output shaft of the variable frequency motor is fixedly connected to a brake ring 1 on the inner side of the rotating seat 1, a plurality of sliders 2 are slidably connected inside the brake ring 1, a spring 2 is fixedly connected to the inner side of the slider 2, a roller is rotatably connected to the outer side of the spring 2, and two brake clamps 1 are rotatably connected to the outer side of the rotating seat 1.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. This utility model achieves frictional dynamic deceleration through the cooperation of brake clamp two and brake ring two, which quickly consumes the motor's kinetic energy and avoids the effects of thermal decay. At the same time, brake clamp one, brake ring one, slider two, roller and spring two form a damping locking structure. When the output shaft is at low speed, static locking is achieved through the cooperation of roller and slot and the damping effect of spring two, which takes into account both dynamic braking efficiency and static locking reliability.

[0012] 2. This utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. When the electromagnet of this utility model is energized, it quickly attracts the electromagnetic adsorption rod, which drives the slider one and the guide slider to move upward to unlock. When the power is off, the spring releases elastic potential energy, which pushes the guide slider to smoothly drive the brake clamp one and the brake clamp two to hold the brake ring, avoiding wear of components caused by hard impact. At the same time, the guide rod one, guide disc one, guide disc two and guide disc three ensure the stability of the brake clamp sliding trajectory, further improving the smoothness of the braking action.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 As shown, this utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit, including a variable frequency motor 1, a connecting flange 2 fixedly connected to the front of the variable frequency motor 1, and a braking module 3 fixedly connected to the front of the connecting flange 2. When the variable frequency motor 1 is running, it drives the internal braking ring 319 and braking ring 315 to rotate synchronously. When braking, the internal components of the braking module 3 are linked to achieve friction deceleration and damping locking.

[0017] like Figure 2 As shown, this utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. The braking module 3 includes a top cover 31, an electromagnet 33 fixedly connected to the top of the top cover 31, an electromagnetic adsorption rod 32 slidably connected to the top cover 31 below the electromagnet 33, a slider 34 fixedly connected to the electromagnetic adsorption rod 32 below the top cover 31, a guide rod 35 fixedly connected to the bottom of the top cover 31, the guide rod 35 slidably connected to the slider 34, a support base 37 fixedly connected to the bottom of the guide rod 35, a spring sleeved on the top of the guide rod 35 above the slider 34, and guide sliders 36 fixedly connected to both the front and rear sides of the slider 34. The top cover 31 is the mounting base for the upper structure, with the electromagnet 33 fixedly connected above it and the electromagnetic adsorption rod 32 slidably connected below it. When the electromagnet 33 is energized, it generates magnetic force to attract the electromagnetic adsorption rod 32.

[0018] like Figure 3As shown, this utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. The output shaft of the variable frequency motor 1 is fixedly connected to a brake ring 319 on the inner side of the rotating seat 39. Several sliders 311 are slidably connected inside the brake ring 319. Springs 313 are fixedly connected to the inner side of the sliders 311. Rollers 312 are rotatably connected to the outer side of the springs 313. Two brake clamps 310 are rotatably connected to the outer side of the rotating seat 39 on the brake ring 319. Guide discs 314 and guide discs 38 are symmetrically arranged and fixed below the top cover 31. Rotating seat 317 is fixedly connected to its inner side. Rotating seat 317 provides rotational support for brake clamps 316.

[0019] like Figure 4 As shown, this utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. Guide disk 1 38 and guide disk 2 314 are fixedly connected to the lower part of the top cover 31. Rotating seat 1 39 and rotating seat 2 317 are fixedly connected to the inner sides of guide disk 1 38 and guide disk 2 314, respectively. Guide disk 3 318 is fixedly connected between rotating seat 1 39 and rotating seat 2 317. Brake ring 2 315 is fixedly connected to the inner side of rotating seat 2 317. Two brake clamps 2 316 are rotatably connected to the outer side of rotating seat 2 317 and brake ring 2 315. When braking, guide slider 36 moves down and pushes brake clamp 1 310 to slide inward, hugging brake ring 1 319. Its inner friction layer contacts brake ring 1 319 to achieve frictional deceleration. At the same time, roller 312 is inserted into the groove of brake clamp 1 310, squeezing spring 2 313 to generate damping force to assist deceleration.

[0020] like Figure 5 As shown, this utility model provides a high-efficiency variable frequency drive motor with an integrated braking unit. Brake ring 2 315 is fixedly connected to brake ring 1 319. The other ends of two brake clamps 2 316 are slidably connected to guide disc 3 318 and guide disc 2 314. The other ends of two brake clamps 1 310 are slidably connected to guide disc 3 318 and guide disc 1 38. Support base 1 37 is fixedly connected to guide disc 2 314 and guide disc 1 38. Two guide sliders 36 are slidably connected to guide disc 1 38 and guide disc 2 314 respectively. On the outside of the second 314, the second brake clip 316 and the first brake clip 310 are slidably connected to the guide slider 36 on their outer sides. When the guide sliders 36 on the front and rear sides of the first slider 34 move upward, the guide sliders 36 slide against the outer sides of the first guide disk 38 and the second guide disk 314 respectively, and push the brake clips 310 and the second brake clip 316 that cooperate with them. The first brake clip 310 slides outward along the slide rails of the first guide disk 38 and the third guide disk 318, away from the first brake ring 319; the second brake clip 316 slides outward along the slide rails of the second guide disk 314 and the third guide disk 318, away from the second brake ring 315.

[0021] The working principle of the high-efficiency variable frequency drive motor of this integrated braking unit will be explained in detail below.

[0022] like Figure 1-5As shown, when the variable frequency motor 1 starts, its output shaft drives the fixedly connected brake ring 315 and brake ring 319 to rotate synchronously, providing power output for the equipment. Then, the electromagnet 33 is energized to generate magnetic force, attracting the electromagnetic adsorption rod 32 below. This causes the slider 34, which is fixedly connected to the electromagnetic adsorption rod 32, to slide upward along the guide rod 35. During the upward sliding of the slider 34, the spring sleeved on the outside of the guide rod 35 is compressed. The guide rod 35 is kept stable by the support seat 37 at the bottom. The support seat 37 is also fixedly connected to the guide plate 38 and the guide plate 314 to ensure the rigidity of the overall structure. The guide sliders 36 on both sides of slider 1 34 move upward accordingly. The guide sliders 36 slide against the outer sides of guide disk 1 38 and guide disk 2 314 respectively, and push the brake clamps 1 310 and 2 316 that cooperate with them. Brake clamp 1 310 slides outward along the slide rails of guide disk 1 38 and guide disk 3 318, away from brake ring 1 319; brake clamp 2 316 slides outward along the slide rails of guide disk 2 314 and guide disk 3 318, away from brake ring 2 315. At this time, brake ring 1 319 and brake ring 2 315 have no braking constraints, the output shaft of variable frequency motor 1 can rotate freely, and the equipment operates normally.The guide plate 318 is fixed between the rotating seat 39 and the rotating seat 317. The rotating seat 39 and the rotating seat 317 are fixed inside the guide plate 38 and the guide plate 314, respectively, providing a stable track for the sliding of the brake clamp. When the variable frequency motor 1 receives the stop command, the electromagnet 33 is de-energized, the magnetic force disappears, and it no longer attracts the electromagnetic adsorption rod 32. The previously compressed spring releases its elastic potential energy, pushing the slider 34 to slide downward along the guide rod 35. As slider 34 moves down and resets synchronously, it drives the guide sliders 36 on both sides to slide downwards along the outer sides of guide disk 38 and guide disk 314. During the sliding process, the guide sliders 36 press against the outer sides of brake clamps 310 and 316. Under the pushing force of the guide sliders 36, brake clamp 310 slides inwards along the slide rails of guide disk 38 and guide disk 318, finally gripping brake ring 319; at the same time, brake clamp 316 slides along the guide disk 314 and... The guide rail of guide disc 318 slides inward, gripping brake ring 2 315. During braking, the friction layer on the inner side of brake clamp 1 310 will first come into close contact with the outer side of brake ring 2 315, and the kinetic energy of the output shaft of variable frequency motor 1 will be quickly consumed by friction to achieve dynamic deceleration. When brake clamp 2 316 grips brake ring 1 319, the slider 2 311 slidably connected inside brake ring 1 319 is squeezed, which drives the roller 312 rotatably connected on the outside to be inserted into the slot on the inner side of brake clamp 2 316. As brake ring 1 319 continues to rotate, when roller 312 moves out of the slot, it squeezes the inner spring 2 313. The damping effect of spring 2 313 further slows down the rotation speed of brake ring 1 319 until the output shaft is completely stationary, achieving static locking and preventing load slippage. The entire process is controlled by the on and off state of electromagnet 33 to control the compression and release of the spring, thereby driving guide slider 36 to drive brake clamp 1 310 and brake clamp 2 316 to complete the unlocking and braking actions. During the braking phase, the vehicle first decelerates rapidly through friction braking, and then achieves smooth locking through the damping action of the roller 312 and the spring 313.
