Abstract

The invention discloses a motor start and stop control device. The motor start and stop control device comprises a manually controlled circuit, a remote circuit and a remote device, wherein the remote circuit comprises a stop normally closed contact 2KV-1, a start normally opened contact 1KV-2, a start control relay 1KV and a stop control relay 2KV, wherein after the stop normally closed contact 2KV-1 is connected in series with a manually controlled normally closed contact SR, the start normally opened contact 1KV-2 is connected in parallel with a manually controlled normally opened contact SB; the start control relay 1KV is connected with a start signal receiving module which is adaptive to a start signal sending module; and the stop control relay 2KV is connected with a stop signal receiving module which is adaptive to a stop signal sending module. The motor start and stop control device has the effect that the control contacts of the motor not only have the function of manually and closely controlling the start and the stop of the motor, but also have the function of remotely controlling the start and the stop of the motor, so that diversified control is realized, and different control methods can be used for different environments and requirements.

Description

technical field [0001] The invention relates to a motor start-stop control device. Background technique [0002] In the control mode of the motor, especially the control mode of the start and stop function of the motor, it is generally controlled manually on the control board at a short distance, and there is also a way of remote control for the start and stop control. However, the control of the motor cannot be simply manual control or remote control, because the manual control method needs to go to the vicinity of the motor every time the operation is started and stopped, which is dangerous. Realize operations such as starting and stopping, but it is not possible to closely observe whether the working state of the motor is normal when starting and stopping. Contents of the invention [0003] The object of the present invention is to provide a motor start-stop control device, which solves the problem of single contact mode for motor start-stop control. [0004] In order...
