Adjustable Speed Drives

  1. Understand the operation, installation, and setup for an alternating current (AC) motor drive.
    Controlling motor speeds to load requirements can increase both the efficiency and performance of a motor installation.
    The primary function of any electronic adjustable-speed drive is to control the
    speed, torque, acceleration, deceleration, and direction of rotation of a machine.
  2. Understand the operation, installation, and setup for a direct current (DC) motor drive.
    Harmonics are high-frequency voltage and current distortions within the power system normally caused by nonlinear loads that do not have a constant current draw, but rather draw current in pulses.
    DC electronic variable-speed drives vary the speed of DC motors with greater efficiency and speed regulation than resistor control circuits
  3. Understand the operation, installation, and setup for PLC motor control.
