Description

Technical Field

[0001] This utility model belongs to the field of brushless motor technology, and in particular relates to a low-loss brushless motor for snow removal machines. Background Technology

[0002] Snowplow motors typically use brushed DC motors or ordinary AC induction motors as their power source. While these traditional motors can meet basic driving requirements, they present numerous problems in practical applications, particularly in terms of performance under high loads, long operating times, and adaptability to harsh environments.

[0003] Traditional brushed motors, due to the physical contact between the brushes and the commutator, generate significant frictional losses and sparks during operation. This not only reduces motor efficiency but also easily causes brush wear, shortening lifespan and increasing maintenance frequency and costs. Furthermore, snow removal operations typically occur in complex environments with low temperatures, high humidity, and even mixed snow and ice, making the brush system highly susceptible to moisture or freezing, leading to starting difficulties or unstable operation. Traditional motor cooling designs are relatively simple, relying primarily on natural heat dissipation or passive air cooling. For example, cooling based solely on surface cooling fins and a few vents is insufficient to effectively manage the heat buildup generated by snowplows under high-intensity continuous operation, resulting in excessive motor temperature rise, affecting output performance and reliability, and in severe cases, even causing motor overheating and burnout.

[0004] To address these issues, we provide a low-loss brushless motor for snowplows. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a low-loss brushless motor for a snowplow, comprising a housing, a motor assembly disposed inside the housing, and a rotating shaft adapted to the motor assembly.

The motor assembly includes a motor housing fixed inside the housing, an arc-shaped heat-conducting block fixed to the inner wall of the motor housing, a stator core located in the middle of the motor housing, winding coils wound around the stator core, an air intake wheel located at the rear of the motor housing, and a drive plate disposed at the front of the motor housing. The rotating shaft is disposed in the middle of the stator core through a motor rotor, and the end of the rotating shaft is fixed to the air intake wheel.

[0007] The present invention is further configured such that the air intake wheel is located inside the air intake perforated plate, and the air intake perforated plate forms an active heat dissipation channel with the heat dissipation groove through the air intake wheel.

[0009] The present invention is further configured such that the drive board is electrically connected to the winding coil for controlling the motor operating state, and the drive board is also provided with a Hall sensor, which is located near the front end of the rotating shaft for detecting the rotor position signal.

[0010] The present invention is further configured such that the motor housing is coaxially disposed inside the outer shell, and the outer shell has openings at both ends for airflow to pass through, the drive plate is fixed to the front of the outer shell, and a gap is left between the two for airflow to pass through.

[0011] The present invention is further configured such that the air intake wheel rotates synchronously with the rotating shaft, and air intake ports are provided at equal intervals around the air intake wheel.

[0012] The present invention is further configured such that the motor rotor is engaged with the center position of the stator core by a ring of permanently magnets, and the rotor core of the motor rotor is fixed to the shaft.

[0013] This utility model has the following beneficial effects:

[0014] 1.

[0026] Example

[0027] Please see Figure 1-5 This utility model relates to a low-loss brushless motor for a snowplow, comprising a housing 100, a motor assembly 300 disposed inside the housing 100, and a rotating shaft 200 adapted to the motor assembly 300. The front periphery of the housing 100 is evenly distributed with heat dissipation grooves 101, and an air intake perforated plate 102 is detachably installed at the rear of the housing 100. The motor assembly 300 includes a motor housing 301 fixed inside the housing 100, an arc-shaped heat-conducting block 304 fixed to the inner wall of the motor housing 301, a stator core 305 located in the middle of the motor housing 301, winding coils 306 wound around the stator core 305, an air intake wheel 302 located at the rear of the motor housing 301, and a drive plate 303 disposed at the front of the motor housing 301. The rotating shaft 200 is disposed in the middle of the stator core 305 through a motor rotor, and the end of the rotating shaft 200 is fixed to the air intake wheel 302.

[0028] Specifically, the air intake wheel 302 is located inside the air intake perforated plate 102. The air intake perforated plate 102 forms an active heat dissipation channel with the heat dissipation groove 101 through the air intake wheel 302. The motor housing 301 is coaxially disposed inside the outer shell 100, and the outer shell 100 has openings at both ends for airflow. The drive plate 303 is fixed to the front of the outer shell 100, and a gap is left between the two for airflow. The air intake wheel 302 rotates synchronously with the rotating shaft 200, and air intake ports are equidistantly arranged on the periphery of the air intake wheel 302.

[0029] Furthermore, the front end of the rotating shaft 200 is movably embedded in the middle of the front part of the housing 100 via a bearing, and the front end of the rotating shaft 200 is connected to the transmission component of the snowplow. The motor rotor is engaged with the center of the stator core 305 via annularly distributed permanent magnets, and the rotor core of the motor rotor is fixed to the rotating shaft 200. The drive plate 303 is electrically connected to the winding coil 306 for controlling the motor's operating state. The drive plate 303 is also equipped with a Hall sensor, which is located near the front end of the rotating shaft 200 for detecting the rotor position signal.

[0030] This embodiment provides a low-loss brushless motor for a snowplow, whose working principle is based on an optimized heat dissipation mechanism and a high-efficiency power conversion mechanism. The motor assembly 300 is fixed inside the housing 100 and includes a motor housing 301, an arc-shaped heat-conducting block 304, a stator core 305, winding coils 306, an air intake wheel 302, and a drive plate 303. The rotating shaft 200 is mounted in the middle of the stator core 305 in conjunction with the motor rotor and is fixed to the air intake wheel 302, achieving synchronous rotation. When the motor is running, the front end of the rotating shaft 200 connects to the transmission components of the snowplow for mechanical output, while the air intake wheel 302 at the end of the rotating shaft 200, when rotating, draws in cold air through the air intake perforated plate 102. This air then passes through the heat dissipation grooves 101 evenly distributed on the front periphery of the housing 100, forming an active heat dissipation channel, effectively reducing the motor temperature. The arc-shaped heat-conducting block 304 further conducts the heat generated inside the motor away, enhancing the heat dissipation effect. The drive board 303 not only controls the current of the winding coil 306 to drive the motor, but is also equipped with a Hall sensor to detect the rotor position signal, ensuring efficient operation of the motor and achieving low-loss and high-efficiency operation, which is particularly suitable for snow removal equipment that requires long-term stable operation.

[0031] When using the low-loss brushless snowplow motor of this invention, first ensure that the motor is correctly installed in the snowplow. The front end of the shaft 200 is movably embedded in the middle of the front part of the housing 100 via a bearing and is accurately connected to the transmission components of the snowplow. Next, connect the motor to the power supply and control system. The drive board 303 will be electrically connected to the winding coil 306, ready to receive control signals to start the motor. When the motor receives the running command, the shaft 200 begins to rotate, driving the intake wheel 302 fixed at its end to rotate synchronously. The air inlets equidistantly arranged around the intake wheel 302 draw in cold air into the motor through the intake perforated plate 102, forming an active heat dissipation channel. This airflow passes through the openings at both ends of the housing 100 and the gap between the front of the housing 100 and the drive board 303, carrying away the heat generated by the motor assembly 300, thereby effectively reducing the motor temperature. During this process, a Hall sensor is positioned near the front end of the shaft 200 to detect the rotor's position signal in real time, precisely controlling the motor's operating state and ensuring efficient and stable motor operation.
