The invention discloses a detecting device and detecting system of a stepping motor so as to improve the detecting efficiency and the detecting precision of the running capability and the driving capability of the stepping motor. The stepping motor detecting device comprises a first conductive structure, an end cover, a second conductive structure and a controller. The first conductive structure is fixed to the end cover and comprises a first electrode and a second electrode, and the first electrode and the second electrode are in signal connection with the controller. The end cover includes an accommodating space for accommodating the second conductive structure, and the end cover is provided with a through hole that cooperates with a rotating shaft of the stepping motor. The end cover rotates with the rotating shaft of the stepping motor. When the end cover is rotated, the second conductive structure turns on or off the first electrode and the second electrode. The controller determines whether the first electrode and the second electrode are in an on-off alternating state or not, and determines that the rotor of the stepping motor runs normally if so, otherwise, determines thatthe rotor of the stepping motor runs abnormally.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a detection device and a detection system of a stepping motor. Background technique [0002] The sweeping function of the air conditioner is usually driven by two sets of drive box devices, each set of drive box devices is provided with a first stepping motor, a second stepping motor and a rack and pinion, wherein the first stepping motor is used to drive the gear to rotate , the second stepping motor is arranged at the end of the rack and moves with the rack. Before the two sets of drive box devices are applied to the air conditioner, they need to be placed on the drive box test stand arranged in the vertical direction at the same time for testing. First of all, it is necessary to drive the gear to rotate through the first stepping motor to drive the rack to move, and to detect whether the two racks trigger the travel switch synchronously to achieve the purpose of d...
