The difference between the inverter and the soft starter
1. Different effects:
The inverter is an electrical device that controls the rotation speed of the motor. It can control the speed and output power by adjusting the output frequency.
Soft promoter is an electrical equipment that reduces the start -up current and the torque when starting the motor. It can avoid the impact and vibration of the motor and supporting equipment when starting, and extend the life of the equipment.
2. The principle is different:
The inverter can control the motor speed and output power by adjusting the output frequency. Generally, PWM technology is implemented.
Soft promoters reduce the impact and vibration during the starting slope and start time by controlling the current, and the circuit such as capacitors, resistors, and inductors is usually implemented.
3. Different scope of application:
The inverter is suitable for the areas that need to adjust the motor speed, such as motor control in industries such as mechanical manufacturing, construction, pharmaceuticals, and food.
