Description

Split type motor and controller integrated device

Technical Field

The utility model belongs to the technical field of motors and controllers, and particularly relates to a split type motor and controller integrated device.

Background

Aiming at the protection of the motor and the voltage of a power grid, four schemes of a traditional thermal relay, a soft starter, a frequency converter and a motor controller are mainly adopted in the field application at present. The traditional thermal relay is low in sensitivity, greatly influenced by environment and low in adjustment accuracy due to the physical characteristics of the traditional thermal relay. The soft starter is biased to the starting process of the motor, and the starting of the motor is controlled by adopting a voltage reduction mode, so that the motor cannot be protected in the working process. The control and protection functions of the frequency converter are strong, and meanwhile, the motor can be regulated, but the price is high. The motor controller can play a good control and protection role on the motor, but the integral motor controller in the current market is too large in size, is unfavorable for sealing and is easy to leak gas.
