Ac Dc Drive

Drives are electromechanical structures that use an electric motor as the key mover instead of diesel engines, turbines of steam and gas, or hydraulics to regulate the motion and procedures of various mechanisms. For example, drives are used in: conveyors, compressor pumps, fans, excavators, ventilators, cranes, electric locomotives, hoists, escalators and cars.

Adjustable speed drive or ASD and Variable-speed drive or VSD designates equipment used to regulate the speed of any machinery. Several industrial processes for instance assembly lines must function at diverse speeds for diverse products. Situations where process conditions demand modification of flow from a pump or fan, altering the speed of the drive may save energy compared to other methods for flow control.

In situations, where speeds may be chosen from numerous different pre-determined ranges, the drive is said to be of adjustable speed commonly. If the production speed can be changed minus steps over a range, the drive is generally referred to as variable speed.

  • AC Drives

An AC Drive is an electronic device that transforms a static frequency and voltage to a modifiable frequency and AC voltage source. It regulates the speed, rotation, horsepower and route of an AC motor.AC Drives are also known as Variable Frequency Drives or VFD's or Adjustable Speed Drives or ASD's.

Advantages

  • Size
  • Cost
  • Trustworthiness
  • Performance

 

  • DC Drives

DC Drives are very beneficial for the use of many applications too.DC Drives function with DC signal or voltage supplies like batteries.In general, a DC drive transforms an Alternating Current or AC into Direct Current or DC to run a DC motor.

Advantages

  • Changeable speed
  • Good speed control
  • Recurrent starting, decelerating and retreating

Ranges

Adjustable and variable speed drives may be purely mechanical, electromechanical, hydraulic, or electronic.
