Product Features

Requires fewer components, has a simple starting method, and is cost-effective, making it more suitable for low-power motors. The current for direct starting of an electric motor is more than 5 times that of normal operation. In theory, as long as the capacity of the power supply line and transformer that provide power to the electric motor is greater than 5-7 times the capacity of the electric motor, it can be started directly. This requirement is easy to implement for small capacity motors, so the vast majority of small capacity motors are started directly without the need for voltage reduction.
Disadvantages
For large capacity electric motors, on the one hand, the power supply lines and transformer capacity are difficult to meet the conditions for direct starting of the motor. On the other hand, the strong starting current impacts the power grid and the motor, affecting the service life of the motor and being detrimental to the power grid.
