OPTIMIZING THE ENERGY DEMAND OF YOUR MOTORS

MOTOR MANAGEMENT SYSTEM

LOSSES & EFFICIENCY

vfd-drive-characteristics

As the load decreases the torque required decreases, so it is possible to reduce the voltage. Torque is proportional to the square of the voltage.

Advantages of reducing voltage

  • Power factor is maintained=reduced current
  • Iron losses are reduced
  • Copper losses are reduced

Induction Motors running at reduced load and under the optimum design load condition are in-efficient. Most LV induction motors are running at below full load therefore running in-efficiently; they may even run for considerable time on very light or no load. Obviously variable speed drives can optimize the load system speed for efficient operation or the driven system but when the load changes it is necessary to optimise the induction motor efficiency and this can be done by reducing the voltage.

With the development of power electronics there is equipment available that can do many functions automatically and respond very rapidly to the load requirements.

LIMITER is a high quality motor management unit which will provide the following:

  • Soft start
  • Controlled shutdown
  • Automatic shutdown
  • Energy reduction to optimise power savings
  • All this can be built into one unit which is fitted in the motor control panel
  • Fixed speed units are available for power control and saving

LIMITER UNIT IS A MOTOR MANAGEMENT SYSTEM THAT OPTIMIZES THE ENERGY DEMAND OF THE MOTOR.

Advantages of LIMITER Power Management System

  • Energy Saving (kWh)
  • Reduced operating vibration
  • Reduced operating temperature
  • Motor overload and Thermal protection
  • LIMITER provides induction motors with some intelligence
  • Increases the operating life of the motor
