1. What is a Soft Start Starter?
A soft start starter is an essential device that gradually increases the voltage supplied to an electric motor during startup, reducing inrush current and mechanical stress. SHUYI’s soft start starter minimizes electrical and mechanical wear, making it a crucial solution for industries aiming to boost efficiency and cut maintenance costs.
2. How SHUYI’s Soft Starter Works
SHUYI’s soft start starter operates through a three-step process:
- Initial Voltage Ramp:
It starts with a low voltage and gradually increases it over time (0.5–30 seconds), allowing the motor to reach full speed smoothly. - Torque Control:
Adjusts torque output based on the load, preventing belt damage and gear failures in conveyor systems or pumps. - Soft Stop Feature:
Reduces voltage gradually during shutdown, avoiding sudden mechanical shocks in applications like elevators.
