A rotor lamination for a motor having a motor air gap width value is disclosed. The rotor lamination includes a main-body portion, a plurality of edges and a plurality of magnet-receiving slots. The main-body portion is centered at a central axis of the motor. The edges are disposed around outside of the main-body portion. The magnet-receiving slots accommodate a plurality of magnets of the motor and locate around the central axis. The magnet-receiving slot has a slot width value in an outward direction extending from the central axis. The magnet-receiving slot and the corresponding edge form a magnet depth value. The magnet depth value is greater than a sum value of a first rate constant multiplied by the slot width value and then subtracted the motor air gap width value, and is less than the sum value of the first rate constant multiplied by the slot width value and then plus the motor air gap width value.

An integrated apparatus of water-cooled motor and driver includes a motor housing and a driver housing. The motor housing includes a motor-housing inner wall, a motor-housing outer wall, an inlet, a heat-dissipation flow channel and an outlet. The motor-housing inner wall surrounds and receives a motor assembly. The motor-housing outer wall surrounds the motor-housing inner wall, and the exterior thereof has a first connecting surface. The inlet is disposed on the motor-housing outer wall. One end of the heat-dissipation flow channel is connected to the inlet, the end contacts and is received between the motor-housing inner wall and the motor-housing outer wall. The outlet is connected to the other end of the heat-dissipation flow channel and is disposed on the motor-housing outer wall. The driver housing receives a driver assembly, and the exterior thereof has a second connecting surface connected with and bonded to the first connecting surface.

A rotor is provided. The rotor includes a main body, a plurality of magnets and a plurality of magnet-receiving slots. The plurality of magnet-receiving slots are disposed on the main body and disposed around a central axis. Each two adjacent magnet-receiving slots are symmetrical to each other. Each magnet-receiving slot includes a slot body and a first flux barrier connected with each other. Each magnet is contained in the corresponding slot body. Each first flux barriers includes a respective arc-cutting start point. A minimum arc-cutting distance is formed between the two respective arc-cutting start points. Each of the two respective arc-cutting start points is extended toward the central axis along an arc with a first arc length radius to define a first arc-cutting end point. The first arc length radius is greater than or equal to 0.2 times of the minimum arc-cutting distance.

Rotor

A rotor assembly for a motor is disclosed. The motor has a minimum air gap width value. The rotor assembly includes magnets, a main-body portion, magnet-receiving slots and arc-trimming portions. Each of the magnet-receiving slots is disposed around a central axis of the main-body portion and locates through the main-body portion for accommodating the corresponding magnet therein. The magnet-receiving slot has a slot width value. The arc-trimming portions spatially correspond to the magnet-receiving slots. Each of the arc-trimming portions and a geometric symmetry center of the corresponding magnet-receiving slot together form an arc-trimming depth value. The arc-trimming depth value is greater than a sum value of a rate constant multiplied by the slot width value and then subtracted 2 times of the minimum air gap width value, and is less than the sum value of the rate constant multiplied by the slot width value and then plus 2 times of the minimum air gap width value.

Rotor assembly and motor using same

A driving mechanism is provided. The driving mechanism connects with a frame and a driving wheel by two ends thereof. The driving mechanism includes a motor housing, a motor assembly and a driving controller. The motor housing supports the frame and defines an inner space. The motor assembly is detachably assembled with the motor housing and located in the inner space. The motor assembly drives the driving wheel. The driving controller is detachably assembled with the motor housing, located in the inner space, and electrically connected with the motor assembly.
