Abstract: A testing system for testing a temperature characteristic of a first motor includes a second motor, a controller, a driver, a load, a temperature sensor, and a temperature recorder. The controller provides a drive command for the driver to drive the second motor. The second motor drives the first motor via a coupling. A current of the first motor is determined by adjusting the resistance of the load. The temperature sensor senses the temperatures of the first motor every a determined time and sends the temperatures to the temperature recorder. The temperature recorder records and transmits the temperatures to the controller for the temperature characteristic test of the first motor.

Abstract: A support device for a shaft extension of a motor, the motor including a flange facing and a shaft, the shaft not protruding outward beyond the flange facing. The support device includes a retainer and a bearing. The retainer includes a receiving chamber. The retainer is fastened to the flange facing of the motor. The bearing includes an inner hole. The bearing is received in the receiving chamber of the retainer. A shaft extension is coupled with the shaft of the motor through the inner hole of the bearing. The shaft extension is supported by the retainer and bearing.

Abstract: An automatic hold time fixing circuit unit includes a first switch having first and second ends connected to data input and output ports. An input end of a memory element is connected to the second end of the first switch. A second switch includes a first end connected to an output end of the memory element and a second end connected to the data output port. A control circuit includes first and second output terminals and first and second input terminals. The first and second output terminals are connected to control ends of the first and second switches. The first and second input terminals allow input of two clocks to the control circuit for controlling connection or disconnection of the first and second switches. The data stored in the memory element can be utilized to fix a hold time of the data, so that correct data can be obtained at the data output port.

Abstract: A cooling apparatus for an electric motor includes a mount to be fixed to and abutted against the electric motor, and a cooling unit installed to the mount. The mount defines at least two channels. The cooling unit connects adjacent said at least two channels to form a passage to allow a cooling fluid flowing in the passage.

Abstract: An assembly mechanism is provided to press an inner stator into a receiving space of an outer stator. The assembly mechanism includes a pressing unit and a first positioning plate. The pressing unit includes a supporting device to support the outer stator, and a pressing device movable relatively to the supporting device. The first positioning plate is attached to a top of the outer stator. The first positioning plate defines an opening forming a clearance fit with the inner stator. The opening receives the inner stator and guides the inner stator to move into the receiving space of the outer stator under a pressing action of the pressing device. An assembly method is also provided.
