Abstract

The invention discloses a testing device of a stepping motor. The testing device comprises a power supply circuit, a resistor circuit, a sampling circuit, a logic circuit, an alarm circuit and a pulse circuit. The resistor circuit comprises a testing sample piece T1 and a standard sample piece T2 which are connected in series and then are grounded. The sampling circuit and the logic circuit are electrically connected with the resistor circuit, and the connecting position is disposed between the testing sample piece T1 and the standard sample piece T2. The sampling circuit, the logic circuit and the alarm circuit are sequentially electrically connected together, and the pulse circuit is electrically connected with the logic circuit. The sampling circuit is used for acquiring a voltage signal of the resistor circuit. The logic circuit is used for acquiring a determination result after an analysis and transmitting the determination result to the alarm circuit. The alarm circuit is used for giving an alarm according to the determination result. The pulse circuit is used for providing a clock pulse for the logic circuit. The testing device of the stepping motor improves the accuracy and the efficiency of a product test.

Description

technical field [0001] The invention relates to the technical field of testing instruments, in particular to a testing device for a stepping motor. Background technique [0002] The short-circuit of the motor is an important indicator for testing the performance of the motor. At present, the resistance value of the stepping motor and the short-circuit fault of the winding are measured with a multimeter, and the test method is inefficient. Due to the diversification of stepping motor products, many motors in the industry have canceled the lead wires of the motor. For pin-type motors without lead-out wires, the multimeter probe cannot be in good contact with the pins, resulting in inaccurate test results and unable to quickly test Faults in the wiring. Contents of the invention [0003] Based on this, it is necessary to provide a fast and accurate testing device for stepping motors to solve the problems of low accuracy and efficiency of existing testing devices.
