Abstract

The invention discloses a motor switch with automatic identification. The invention relates to a motor switch device, in particular to a travel switch device of a direct current motor and an automatic stop device after blockage. The motor switch is characterized in that: a relay control end for supplying power to the motor is electrically connected with a thermistor of a resettable fuse connected with a relay common end in series to determine the blockage of the motor, the operation of the relay control end is stopped according to the great resistance of the thermistor of the resettable fuse, generated after the motor is blocked, and the working power supply of the motor is shut down. According to the invention, the motor switch is low in cost, not easy to damage, can realize automatic identification and work, and realizes ideal motor protection effect.

Description

Technical field [0001] The invention relates to a motor switch device, in particular to an automatic travel switch of a DC motor and an automatic shut-off device after a locked rotor. Background technique [0002] Before the application date, the work of the motor was manually controlled to turn on and off the power supply. When the motor rotated and encountered resistance and stalled, if the power supply was not turned off in time, the motor would be burnt out. [0003] It is also known that after the car is locked, all the windows need to be closed automatically. The additional window closer uses the window motor to work on a delayed basis to close the windows. Different, with a strong unity. If the delay is too long, the window motor will block and stall. [0004] In order to solve the problem of motor stalling, the current new technology is: a micro-value resistor is connected in series in the motor circuit, and the two ends of the resistor are connected to the current...
