1. DC Series Motor. Since it has high starting torque and variable speed, it is used for heavy duty applications such as electric locomotives, steel rolling mills, hoists, lifts and cranes.
Where are DC motors used in industry?
DC Motor Applications in Industries
- DC series motors are widely used for electrical traction applications, i.e, these motors are widely used in electric locomotives, rapid transit systems and trolley cars.
- DC series motors are employed in cranes, hoists and in conveyers because of high staring torque capability.
Why DC motor is used in industrial application?
For industrial applications that require constant low-speed torque or precise speed adjustments, DC motors are likely going to be the best choice. They’re easier to maintain and provide superior speed control while eliminating the problems caused by harmonic effects.
Which type of DC motor is used for?
Compound DC Motors
Compound DC motors or compound wound motors have both series and shunt field windings. These types of motors offer good starting torque, but they may have control problems in variable speed drive applications. These motors can be connected to two arrangements: cumulatively and differentially.
Which type of dc motor connection is recommended for industrial starting application?
Series wound DC motors are best for applications that require high startup torque, without the need for speed regulation. Like a shunt motor, as a load is applied to a DC series motor, the motor speed decreases, which reduces the back EMF and increases the net voltage.
What are the 3 types of DC motors?
Main Types of DC Motors
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
- Shunt DC Motors. …
- Compound DC Motors.
What is the principle of DC motor?
DC motors operate on Faraday’s principle of electromagnetism which states that a current-carrying conductor experiences a force when placed in a magnetic field.
What are the advantages of DC motor?
Below are some advantages of DC motors that you should consider:
- Good speed control. DC motors offer highly controllable speed. …
- High torque. …
- Seamless operation. …
- Free from harmonics.
What are the disadvantages of DC motor?
Disadvantages of DC motors
- High initial cost.
- Increased operation and maintenance cost due to the presence of commutator and brush gear.
- Cannot operate in explosive and hazard conditions due to sparking occur at brush (risk in commutation failure)
How do you build a DC motor?
What You Need:
- Insulated copper wire.
- Black permanent marker (such as a Sharpie)
- Small neodymium disc magnets.
- D-size battery.
- Battery holder (sticky tack or modeling clay can be used instead)
- Large rubber band (not needed if using a battery holder)
- 2 large paperclips.
What are the two main parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What is the full form of dc motor?
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy.
What are the parts of a DC motor?
These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes.
What is the most common type of dc motor?
Mainly there are two types of DC Motors. One is Separately Excited DC Motor and other is Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor.
Which motor has high starting current?
The induction motor draws a high starting current as compared to the running condition. The starting current of the induction motor is about 5 or 6 times the motor full load current.
What is DC motor with diagram?
