Jun 02, 2021 Soft Starter
Soft Electric Motors often require large amounts of electricity during their accelerating to the nominal speed, a Soft Starter can be used to limit the surge of current known as “inrush current” and torque of the electric motors, resulting in a safer, smoother and gradual start-up.
Soft starters will protect your electric motor from possible damage and at the same time extend the lifespan of your electric motor and the whole system by declining the heating caused by frequent start/stops, reducing the mechanical stress on the motor, its shaft and reducing the electrodynamic stresses on the power cables.
Large inrush current also places a high demand on the electrical supply system, which results in extra cost.
Soft Starters for motors are commonly used in industrial applications that have a high inertia load that requires a large inrush of current.
The main component of a soft starter is a Triac which is designed to limit the applied voltage to the motor.
Triac consists of two back-to-back Thyristors or SCRs. When an internal pulse is applied to its gate it allows current to flow which then sends current out to our motor.
The pulses are sent based on ramp time so the current will be slowly applied to the motor. This will allow our soft start motor to start slowly reducing torque and inrush current.
Soft starter is available through Quick Time Engineering Inc.
