What are 3 types of motor controls?

There are four basic motor controller and drive types: AC, DC, servo, and stepper, each having an input power type modified to the desired output function to match with an application.

What are motors and controls?

Motor controls can ideally be identified as a group of devices that govern the performance of an electric motor in a predefined manner. Motor controls are also known as motor controllers.

What is basic motor control?

Basic Principles of Motor Controls. device will operate to open the circuit because of the increased heat caused by the current running through it. A magnetic starter or other motor controllers may include overload devices, or they may be an integral part of the motor, particularly with small motors.

What are the functions of a motor control?

Motor control refers to manual or automatic methods for starting, stopping, controlling speed, reversing, and protecting a motor. These controls are achieved using a variety of circuits, connections and sensors.

What are the two types of industrial motor control?

Motor types for industrial electric drives

DC Shunt Motor. Cumulative Compound Motor. Three phase Synchronous Motor. Squirrel Cage Induction Motor.

What is motor control in human body?

Motor control is the regulation of movement in organisms that possess a nervous system. Motor control includes reflexes as well as directed movement. … Successful motor control is crucial to interacting with the world to carry out goals as well as for posture, balance, and stability.

How do you control a motor?

Thus, the speed of a DC motor can be controlled in three ways:

  1. By varying the supply voltage.
  2. By varying the flux, and by varying the current through the field winding.
  3. By varying the armature voltage, and by varying the armature resistance.

What are the two basic elements of a motor starter?

Contactor Construction and Operation. A magnetic motor starter has two basic parts: the magnetic contactor and an overload relay .

Why starter is used in AC motor?

This rotor emf drives the current through the rotor. … Therefore, a starter is necessary to limit this starting current to avoid damage to the motor as well as to other adjoining equipment. A starter is a device that reduces initial high current of the motor by reducing the supply voltage applied to the motor.

What are the types of starters?

Various types of starters are as follows:

  • Stator resistance starter.
  • Star delta starter.
  • Autotransformer starting.
  • Rotor resistance starters.
  • Variable stator frequency starting.


What is the most important function of control system?

“One of the major functions of most control systems is to provide protection for both the circuit components and the motor. Fuses and circuit breakers are generally employed for circuit protection, and over load relays are used to protect the motor.”

What are the four major factors when installing a motor control system?


  • power source that is need for operate machine.
  • motor type that is depend on our work output.
  • motor connection need horse power and service factor etc.
  • environment that is also important for outside of equipment with dust and moisture etc.
  • controller type it is depend upon type of motor and its purpose.


Which motor is mostly used in industry?

3-phase AC induction motors are the most widely used motors in industrial and commercial applications.

Which motor is used in small lathes?

DC shunt motor is used for driving constant speed line shafts, lathes, vacuum cleaners, wood-working machines, laundry washing machines, elevators, conveyors, grinders and small printing presses etc.

Which motor is used in tramways?

The DC motor was the mainstay of electric traction drives on electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. The most notable system to adopt such trams was in Paris. D.C. series motor A.C. three phase motor AC.
