Abstract

The invention relates to a motor with a reversal and locked-rotor protection structure, which comprises a motor body, a fixed base and a protection structure, and the motor body is fixed on the rear side of the top surface of the fixed base, the protection structure is fixed on the front side of the top surface of the fixed base, and the motor body is connected to the inner side of the rear end ofthe protection structure; and the protection structure is composed of a protection device shell, an anti-reversing and anti-blocking structure, a connecting rear cover and a fixing bolt. According tothe invention, the setting of motor stalling processing is optimized, the traditional processing mode that the motor stalling cannot be effectively solved is changed, the motor stalling condition iseliminated by adopting a simple and convenient structure, the structure not only can solve the stalling problem, but also can enable the motor to reversely rotate to prevent damage to auxiliary connection equipment, the equipment structure is detachably arranged, internal parts can be replaced, and the equipment structure belongs to a disposable structure, is convenient to replace and is suitablefor popularization and application.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to an electric motor with reverse and locked-rotor protection structures. Background technique [0002] Motor stalling is a situation in which the motor still outputs torque when the speed is 0 revolutions, and it is generally mechanical or artificial. The phenomenon that the motor cannot start or stop rotating due to excessive motor load, dragging mechanical failure, bearing damage and sweeping. When the motor is locked, the power factor is extremely low, and the current when it is locked (called locked rotor current) can reach up to 7 times the rated current. If the time is too long, the motor will be burnt out. In order to ensure the safety of the motor, a reverse and a motor with a locked-rotor protection structure. Contents of the invention [0003] The object of the present invention is to provide a kind of electric motor with reversing and locked-rotor protection structure,...
