Description

Motor locked rotor detection tool Technical Field The utility model belongs to the technical field of motor detection equipment, and relates to a motor locked rotor detection tool. Background When the motor is in normal power-on operation, the rotor cannot rotate or the rotation speed drops to be close to zero rapidly due to mechanical blockage, excessive load and the like, and the state is called motor locked-rotor. At this time, the motor is in a locked state, which can cause abnormal increase of current and serious heating of windings, and if the motor is not detected and processed in time, the motor can be burnt out, the circuit is overloaded and even safety accidents can be caused. In order to prevent accidents, a motor stall protection device is generally arranged in the motor, and when the temperature rises to a preset temperature (for example, 155 DEG or more), a power supply is cut off, so that the motor stops working. Therefore, when the motor leaves the factory to be detected, the locked rotor protection device of the motor needs to be determined to work normally. The Chinese patent application CN118191597A (publication day: 2024-06-14) discloses a device and a method for testing motor locked rotor, which relate to the field of motor locked rotor testing and comprise an L-shaped test frame, wherein the top end of a transverse plate part of the test frame is provided with a placing platform which is adjustable in height and is used for placing a motor to be detected, one side of the placing platform, which is positioned at the tail end of the motor, is provided with a tight-supporting limiting mechanism for supporting the position of the motor, and the placing platform is in transmission connection with the tight-supporting limiting mechanism through a connecting piece.
