Description

Technical Field

[0001] This utility model specifically relates to the field of motor testing technology, and more specifically to a motor testing device. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a current-carrying coil (stator winding) that acts on the rotor (such as a squirrel-cage closed aluminum frame) to create a magnetoelectric torque. Electric motors are classified into DC motors and AC motors based on the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous (the stator magnetic field speed and rotor rotation speed are not synchronized). An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] Chinese Utility Model Publication No. CN 116609654 A discloses a motor testing platform, relating to the technical field of motor testing equipment. It includes a platform body; a sensor assembly, which includes a sensor body and a sensor sensing ring disposed outside the sensor body, the sensor sensing ring being mounted on the top of the platform body; and a companion motor assembly, which includes a companion motor body mounted on the top of the platform body.

[0004] The aforementioned motor testing platform is used to test the voltage, current, input power, torque, speed, output power, and efficiency of the motor body. However, when the motor is running, it generates vibrations, which may cause changes in speed and torque, making testing inconvenient. To address this, we provide a motor testing device that transmits the motor's power through a linkage rod, allowing for the detection of speed and torque when the motor vibrates, thus effectively overcoming the aforementioned problems.
