In industrial applications, it’s important to have drives that can control the speed of the motor.
These drives are commonly referred to as AC/DC drives and can operate at an adjustable speed.
The benefits of using a variable-speed drive include:
Improved energy efficiency – By reducing the motor speed, you can reduce the energy consumption of your motor.
Lower operating costs – By reducing energy consumption, you can reduce your operating costs over time.
Reduced noise and vibration – By reducing the motor speed, you can also reduce noise and vibration in the motor.
Increased flexibility – Variable-speed drives are ideal for applications that require flexibility in speed and torque.
Improved performance – Variable-speed drives are ideal for applications that require high-performance levels from the motor.
