Problems solved by technology

[0002] In the field of motor control, when the motor is blocked, if the blocked state is not released in time or the power is cut off, the power supply will continuously apply a large current to the motor, which may cause damage to the controller or the motor; There are many ways to rotate, such as detecting the current input to the motor through the software control system to determine whether the motor is in a locked-rotor state, or using a displacement sensor connected to the software control system to detect the motor rotor position signal to determine whether the motor is locked-rotor. Microprocessor, the cost is relatively high, and the output torque cannot be maintained after power off

Abstract

The invention relates to a locked-rotor power-off device which comprises an input disc, an output disc, a locked-rotor trigger piece, a locked-rotor switch, a brake stalling module and a shell. The input disc and the output disc are connected with one or more energy storage elastic elements; the brake stalling module comprises a brake device and a stalling switch; after the motor is provided with the locked-rotor power-off device, the motor is automatically powered off or stopped in case of locked rotor or overload, certain torque output is kept under the action of the energy storage elastic element after the motor is powered off or stopped, and the motor is automatically powered on when locked rotor is relieved; the electric push rod capable of replacing a cylinder can be manufactured in cooperation with a lead screw, a rotary cylinder can be replaced in cooperation with a reduction gearbox, or a product capable of replacing a finger cylinder can be manufactured, and a gear of the reduction gearbox can be protected.

Description

technical field [0001] The invention relates to the field of electromechanical technology, in particular to a locked-rotor power-off device. Background technique [0002] In the field of motor control, when the motor is blocked, if the blocked state is not released in time or the power is cut off, the power supply will continuously apply a large current to the motor, which may cause damage to the controller or the motor; There are many ways to rotate, such as detecting the current input to the motor through the software control system to determine whether the motor is in a locked-rotor state, or using a displacement sensor connected to the software control system to detect the motor rotor position signal to determine whether the motor is locked-rotor. Microprocessor, the cost is relatively high, and the output torque cannot be maintained after power off. Contents of the invention [0003] The invention proposes a locked-rotor power-off device, which automatically powers o...
