The motor driver 3 includes a motor driver housing 31 (hereinafter, referred to as a driver housing 31) and a driver circuit 32, and the driver circuit 32 is disposed in the driver housing 31 and electrically connected to the motor 2 to drive the motor 2 to rotate. For example, the driver circuit 32 includes a plurality of power transistors, and the driver circuit 32 may be fabricated on a circuit board mounted within the driver housing 31. In addition, the driver circuit 32 may be a frequency converter, an inverter, a converter, or the like, depending on the kind of circuit of the motor 2.

In addition, the driver circuit 32 may be electrically connected to an external control system, which controls the motor speed, for example, the external control system outputs a control signal to the driver circuit 32; alternatively, the driver circuit 32 may also have a controller that outputs control signals to a driver of the driver circuit 32, such as a frequency converter, inverter or converter, etc., that drives the motor 2 in rotation. The control signal controls the current, voltage, frequency, etc. output to the motor 2 by the driver circuit 32, thereby controlling the rotational speed of the motor. The control signal is, for example, a PWM signal or a digital signal, which may carry instructions.

Referring to fig. 1A to 1C, fig. 1B is a schematic view of the motor sleeve in fig. 1A, and fig. 1C is a front view of the motor apparatus in fig. 1A.

The inner surface 112 of the motor sleeve 1 is assembled with the motor 2, and the heat generated by the operation of the motor 2 is firstly transmitted to the motor housing 21 and then transmitted to the motor sleeve 1. The outer surface 111 of the motor sleeve 1 is assembled with the motor drive 3, in which motor drive 3 the driver circuit 32 generates heat energy during operation, which heat energy is conducted first to the driver housing 31 and then to the motor sleeve 1. After the heat energy is conducted to the motor sleeve 1, the heat is dissipated through the base fins 14 of the motor sleeve 1, so that the heat dissipation is accelerated and the effect that one motor sleeve 1 can dissipate heat at the same time instead of the motor 2 and the motor driver 3 is achieved.

The motor sleeve 1 is arranged between the motor 2 and the motor driver 3, and the motor driver 3 is not directly fixed at the upper end of the motor 2 by screw fixation or slide connection, thereby reducing the vibration of the motor 2 to be transmitted to the motor driver 3.

The annular motor sleeve 1 is sleeved on the motor 2, and the annular extending cooling fins are used to conduct the high-temperature acceleration of the rotor and the stator of the motor 2 out of the motor casing 21. Because the motor 2 has no heat sink, the annular motor sleeve 1 can be sleeved on the motor 2 and then locked.

The first coupling structure 311 and the second coupling structure 13 are coupled together by screws or rivets, and the first coupling structure 311 and the second coupling structure 13 are holes, for example. The number of the first coupling structures 311 is not limited to one, and the number of the second coupling structures 13 is not limited to one, for example, the number of the first coupling structures 311 and the second coupling structures 13 is four, respectively.

The first and second branch fins 113 and 114 are thermally connected to the driver housing 31. For example, the first and second branch fins 113 and 114 may directly or indirectly contact the driver housing 31, thermally connected to each other by thermal conduction. The indirect contact is between the first and second branch fins 113 and 114 and the driver housing 31, and there is also another heat conducting element to connect.

For example, the number of the first fixing structures 212a is four, and the number of the second fixing structures 12a is four.

The annular motor sleeve 1a is sleeved on and fixed on the heat sink 215 of the motor 2a to serve as an extension of the heat sink, and surrounds the surface of the motor 2a to form a heat conducting area larger than the original surface so as to achieve a rapid heat conducting effect. The driver housing 31 may be a heat conducting design, combined with the ring motor sleeve 1a to achieve a fast heat conducting effect at the driver components. The fan 4 is externally hung and arranged outside the annular motor sleeve 1 to achieve a quick heat dissipation effect, and can also achieve the effect that one motor sleeve 1 can replace the motor 2a and the motor driver 3 to dissipate heat simultaneously.

For example, in fig. 1A and fig. 2, the sleeve bases 11 and 11A may be a single ring-shaped piece, and two ends of the ring-shaped piece are connected and fixed at the fixing portion 116 to form a sleeve shape.
