Which control technique is used for induction motor?
The purpose of the scalar control technique is to control the magnitude of the chosen quantities. For the Induction Motor (IM) the technique is used as Volts/Hertz constant. used in industrial variable speed drive system with vector control technology. This method requires a speed sensor for speed control.
What is motor control circuit?
A motor control circuit, for the most part, is simply a. switch (or group of switches) and a motor. If you keep. the word “switch” in mind, it helps keep the intimidat- ing subject of “motor control” in its proper context.
How does a motor control circuit work?
The start and stop action of the motor is determined by the control circuit , which energizes the magnetic motor starter, pulling in or dropping out the armature that then opens or closes the power contacts. The current that goes to the motor then runs through the heater elements of the overload relay .
What are the different types of motor control techniques?
Types of Motors and Control Techniques
- PMSM Motor Control.
- BLDC Motor control.
- Speed Control of Switched reluctance motor(SRM) Using dsPIC.
What is the speed control techniques used in vector control?
There are two vector control methods, direct or feedback vector control (DFOC) and indirect or feedforward vector control (IFOC), IFOC being more commonly used because in closed-loop mode such drives more easily operate throughout the speed range from zero speed to high-speed field-weakening.
What are the types of motor control circuits?
There are mainly there are three types of motor control circuits:
- Direct On Line Starter (DOL starter)
- Star Delta Starter.
- Auto Transformer Starter.
What are control circuits?
A control circuit is a special type of circuit used to control the operation of a completely separate power circuit. Consider a 1,000 horsepower, large industrial motor driving a water pump. The motor is connected to a high voltage electrical supply of 2,400 volts.
What is VF control of induction motor?
V/F control is an induction motor control method which ensures the output voltage proportional with the frequency, so it maintains a constant motor flux, preventing weak magnetic and magnetic saturation phenomenon from happening.
What is vector control in induction motor?
Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector.
How do you make a motor control circuit?

What are the applications of induction motors?
Used in almost every process, induction motors are mainly used in water pumps, kitchen appliances, fans and air conditioners, automobiles and common industrial machinery like boiler pumps and compressors.
What is three phase motor control?
Speed Control of Three Phase Induction Motor . A three phase induction motor is basically a constant speed motor so it’s somewhat difficult to control its speed. The speed control of induction motor is done at the cost of decrease in efficiency and low electrical power factor.
What is induction motor drive?
Induction motors are largely utilized in drive applications like fixed-speed and variable-frequency drive. Advancement in power electronics is expected to increase the market share of the induction motor market. Induction motor also serves as an alternative of a permanent magnet in the electric vehicles.
What is three phase induction?
A three phase induction motor runs on a three phase AC supply. Construction of a 3 phase induction motor. Just like any other motor, a 3 phase induction motor also consists of a stator and a rotor. Basically there are two types of 3 phase IM – 1.
