LEESON® Industrial AC/DC Controls
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.
