Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a three-phase brushless motor. Background Art

[0002] A three-phase brushless motor is a motor driven by direct current through an inverter circuit. It lacks brushes and a commutator. Comprising a motor and a driver, it is a typical mechatronic product. Its armature winding is wound on the stator, while the excitation is on the rotor, which is a permanent magnet. Electronic commutation replaces the mechanical commutation of brushed motors, and the current direction is controlled by the switching of power transistors. To ensure synchronization between the switching signal and the position of the rotor's magnetic poles, a sensor that detects the rotor's position angle is required.

[0003] Currently, three-phase brushless motors are generally installed on mounting racks or mounting tables in equipment rooms. Since the motor is mounted on the mounting rack or mounting table using nuts and bolts to lock and restrict it, when the installation space is narrow, the nuts and bolts are on both sides of the mounting rack or mounting table, making it difficult for personnel to tighten the motors. This is especially true when the space in the equipment room is compact. In addition, the nuts and bolts can easily slip out of the hands and fall into the small operating space during disassembly and installation, making it inconvenient to remove them.

[0006] It should be noted in the solution that mounting holes are provided near the four corners of one end face of the fixed end seat, and the externally threaded hollow column, the adjustment slide button and the reinforcement ring are slidably inserted into the mounting holes.

[0007] It is further worth mentioning that the four corners of the brushless motor body are provided with positioning slots, the side surface of the positioning slider is fixed with a translation guide block, and the translation guide block is slidably connected in the positioning slots of the brushless motor body.

[0008] It should be further explained that the eccentric steering rod passes through the hollow cavity of the externally threaded hollow column, and an operating knob is fixed to one end of the eccentric steering rod extending out of the position adjustment slide button.

[0009] As a preferred embodiment, the eccentric steering rod is rotatably connected to the position adjustment slide button, and an anti-slip gasket is fixed to one end surface of the eccentric turntable.

[0011] Compared with the prior art, the three-phase brushless motor provided by the present invention has at least the following beneficial effects:

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] See also Figure 1-4 The utility model provides a three-phase brushless motor, including a brushless motor body 1, a fixed end seat 2 is fixed at one end of the brushless motor body 1, and a positioning locking mechanism is provided at the four corners of the brushless motor body 1.

[0022] This solution has the following working process: before use, the brushless motor body 1 is placed on the equipment mounting platform through the fixed end seat 2. At this time, the mounting hole 3 of the fixed end seat 2 is aligned with the mounting hole of the mounting platform. During installation, the eccentric steering rod 10 is rotated from the operating knob 11 on the adjustment slide button 7 to drive the eccentric turntable 9 to rotate eccentrically along the reinforcement ring 8. In this way, the eccentric turntable 9 with the protruding external thread hollow column 5 can provide an anti-detachment effect that limits the withdrawal at the end that passes through the preset mounting hole on the mounting platform. In conjunction with the locking knob 6, the brushless motor can be locked in the front operating space, which improves the disadvantage that the disassembly and assembly of traditional brushless motors requires the use of bolts and nuts arranged in the back operating space, which is not convenient for loosening and tightening operations.

[0023] According to the above working process, it can be known that the eccentric turntable 9 with the protruding external thread hollow column 5 can provide an anti-slip function to limit the withdrawal at one end passing through the preset mounting hole on the mounting platform, and cooperate with the locking knob 6 to realize locking the brushless motor in the front operating space, thereby improving the disadvantage that the disassembly and assembly of the traditional brushless motor requires the use of bolts in the front operating space and the arrangement of nuts in the back operating space, which is not convenient for loosening and tightening operations.

[0024] Further as Figure 3 As shown, it is worth mentioning that the four corners of the brushless motor body 1 are provided with adjustment grooves 4, and the side surface of the adjustment slide button 7 is fixed with a translation guide block 13, and the translation guide block 13 is slidably connected to the adjustment groove 4 of the brushless motor body 1. During use, the adjustment slide button 7 slides along the adjustment groove 4 of the brushless motor body 1 through the translation guide block 13, so that the length of the externally threaded hollow column 5 entering the mounting table can be adjusted and adapted to the depth of its preset mounting hole. In addition, the way in which the externally threaded hollow column 5 is preset on the brushless motor body 1 can reduce the difficulty of positioning and the trouble of easy falling during disassembly and assembly.

[0025] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that the eccentric steering rod 10 passes through the hollow cavity of the externally threaded hollow column 5, and an operating knob 11 is fixed to one end of the eccentric steering rod 10 extending out of the adjustment slide button 7.

[0026] Further as Figure 4 As shown, it is worth noting that the eccentric steering rod 10 is rotatably connected to the position adjustment slide button 7, and an anti-slip pad 12 is fixed to one end surface of the eccentric turntable 9.

[0027] Further as Figure 1 As shown, it is worth noting that the eccentric steering rod 10 is penetrated by an anti-slip pad 12, the end of the eccentric steering rod 10 away from the operating knob 11 is fixed on the eccentric turntable 9, and an electrode shaft 14 is provided at one end of the brushless motor body 1.

[0028] In summary: the eccentric turntable 9 of the protruding externally threaded hollow column 5 can provide an anti-detachment function to limit the withdrawal at one end passing through the preset mounting hole on the mounting platform, and can be used in conjunction with the locking knob 6 to lock the brushless motor in the front operating space, thereby improving the disadvantage that the disassembly and assembly of traditional brushless motors requires the use of bolts in the front operating space and nuts arranged in the back operating space, which is inconvenient for loosening and tightening operations; the length of the externally threaded hollow column 5 entering the mounting platform can be adjusted to adapt to the depth of its preset mounting hole, and the way in which the externally threaded hollow column 5 is preset on the brushless motor body 1 can reduce the difficulty of positioning and the trouble of easy falling during disassembly and assembly.
