Multi-rotor unmanned aerial vehicle part detection device

The invention discloses a multi-rotor unmanned aerial vehicle part detection device. The multi-rotor unmanned aerial vehicle part detection device comprises a horizontal base and movable equipment; the movable equipment is mounted on the horizontal base; and the movable equipment comprises a cylindrical chuck plate, a laser tachometer, an alternating current ampere meter, a direct current ampere meter and a motor testing instrument. According to the multi-rotor unmanned aerial vehicle part detection device, the speed is measured by using the laser tachometer in the vertical direction of an unmanned aerial vehicle propeller blade; an output current of the an electronic speed controller is checked by using the alternating current ampere meter to judge whether the electronic speed controlleris in a good condition or not; performances of the electronic speed controller and the motor are judged by using the motor testing instrument; and a real-time voltage value of a battery is read by using the direct current amp
