What's the difference between soft starter and inverter ?
Soft start and inverter are two different concepts related to the control of electric motors.
A soft start is a device used to control the starting current of a motor. When a motor starts, it can draw a very high current, which can damage the motor and the electrical system. A soft start device gradually increases the voltage to the motor, reducing the inrush current and allowing the motor to start smoothly. Soft start is typically used for AC induction motors and is often integrated into the motor starter or motor control center.
On the other hand, an inverter is a device that can control the speed and torque of an AC motor by varying the frequency and voltage of the power supplied to it. An inverter converts the incoming AC voltage into DC voltage, which is then used to generate a new AC waveform with a variable frequency and voltage. This allows the motor to operate at different speeds and with different torques, making it suitable for a wide range of applications. Inverters are often used in HVAC systems, conveyor systems, and other industrial applications.
In summary, while both soft start and inverter are related to the control of electric motors, a soft start is primarily used to control the starting current of a motor, while an inverter is used to control the speed and torque of a motor by varying the frequency and voltage of the power supplied to it.
