Abstract: A multifunctional load test device includes a drive, a motor to be tested, a load motor and an inverter. The drive is electrically connected to civil power. The motor to be tested is electrically connected to the drive and powered by the drive and controllably drivable by the drive. The load motor is drivable by the motor to be tested to produce counter electromotive force. The inverter is electrically connected to the load motor to rectify the counter electromotive force into power identical to civil power.

Abstract: An absolute position readout apparatus includes an encoder device and a readout device. The readout device includes multiple first and second magnetic sensing components that correspond to an absolute track of the encoder device, and a third magnetic sensing component and a fourth magnetic sensing components that correspond to an incremental track of the encoder device. The third magnetic sensing component is configured to be spaced apart from the fourth magnetic sensing component by a specific distance, so as to prevent misreading of absolute position information from the first or second magnetic sensing components being at positions corresponding to boundaries between adjacent magnetized regions of the absolute track.
