Soft starter is a motor control device that integrates motor soft start, soft stop and various protection functions. It is connected in series between the power supply and the controlled motor. Soft starters can be used in various applications where 3-phase squirrel-cage asynchronous motors do not require speed regulation.
According to the voltage level of the adapted motor, XICHI soft starters are divided into low voltage soft starters (CMC series_380/690/1140V) and high voltage soft starters (CMV series_3/6/9kV).
CMC-MX: Built-in Bypass
How to choose a model:
1. First, confirm that the motor is a squirrel-cage asynchronous motor.
2. Understand the parameters on the motor nameplate. For example, the model of the motor, rated current, rated power, etc.
3. Load type.
For equipment with light starting load(e.g. pumps, fans, compressor, etc.), select the model according to the rated power of the motor;
For heavy loads(e.g. crushers, ball mills, elevators, long belts, mixers, Roots fans, etc.), you can consider choosing a model that is one grade larger than the standard configuration, and at the same time properly consider the heat dissipation factor and whether the protection function is complete.
4. Most soft starters are installed in cabinets. Know the size of the soft starter and whether the bypass is built in.
Bypass: reduce the heat loss of the thyristor and improve the efficiency of soft start. It is also possible to use a single soft starter to start multiple motors.
No-bypass type: It is often used for motors that repeatedly work for a short time, and has the effect of light load and energy saving.
