Abstract

The invention provides a conical motor stop brake system; a conical motor rotates under the drive of a frequency changer; the system comprises a short-circuit control unit and a timer unit, wherein the timer unit is used for starting to time when the frequency changer stops outputting and outputting a first signal after a first time length is reached, and starting to time after an output end of the frequency changer is in short circuit and outputting a second signal after a second time length is reached; and the short circuit control unit is used for making two optional phases of the output end of the frequency changer in short circuit after receiving the first signal, and breaking the connection between the phase lines of the output end of the frequency changer after receiving the second signal. The invention also provides a corresponding method. Through making the phase lines of the output end of the frequency changer in short circuit when the conical motor is stopped, the residual magnetism in the conical motor can be eliminated rapidly, and thus the conical motor can close a brake rapidly.

Description

technical field [0001] The invention relates to the field of control of conical motors, and more specifically relates to a parking brake system and method for a conical motor. Background technique [0002] Cone motor (electric hoist) is a three-phase asynchronous motor with its own brake, whose stator and rotor are conical. It integrates power and braking force. This kind of motor has the characteristics of compact structure, small size, light weight, large starting torque, fast and reliable braking, and safe use. Because of its simple structure and convenient use, it is widely used in small and medium-sized lifting sites. [0003] The conical motor is suitable for frequent starting, braking and alternating forward and reverse operation. Its working principle is: the inner cavity of the stator of the motor and the shape of the rotor are conical, forming an electromagnetic brake device. The electromagnetic brake device is based on the conical motor. The joint action between ...
