Description:

• A Variable Speed Drive (VSD) converts a fixed-frequency alternating current (AC) source into a variable-frequency AC supply.
• This regulates power consumption and mechanical power output, allowing the motor to operate at the most efficient speed for both the motor and the process.
• Motor speed can be controlled based on process feedback, such as flow rate, temperature, or pressure, resulting in improved process control.
• This allows for exact regulation of the motor speed across a wide range.
• As a result, VSDs provide extremely fine electrical motor control, allowing motor speeds to be ramped up and down while remaining at the appropriate speeds.
• Motors use only the energy required, rather than running at a constant (fixed) speed and consuming an excess of energy.
