The starting point for specifying a motor is the supply voltage, the horsepower rating, and the base speed for the particular application. Another important consideration is the enclosure. Will the motor have mounting feet, a flange on the drive end, or can it have both?
How do you select a motor for a particular application?
A constant or variable torque and horsepower will be required for the industrial motor depending on the type of load the motor is driving. The size of the load, the required speed, and acceleration/deceleration—particularly if it’s fast and/or frequent—will define the torque and horsepower that is required.
What are the applications of induction motors?
The single-phase induction motors are used in low power applications. These motors are widely used in domestic and industrial applications.
Some of the applications are mentioned below:
- Small fans.
- High speed vacuum cleaners.
- Electric shavers.
- Drilling machines.
What are the main criteria in selection of motor?
Motor Selection- The motor selection process is not as simple as you might think. While selecting a motor, you will need to concentrate on many things e.g. Motor Speed, Motor Power Ratings, Motor load torques, Motor losses, Motor Efficiency etc.
What are the applications of a motor?
The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
What are the factors governing the selection of electric drives for any particular application?
Some of the important factors are. 1. Steady State Operating conditions requirements: Nature of speed torque characteristics, speed regulation, speed range, efficiency, duty cycle, quadrants of operation, speed fluctuations if any, ratings etc 2.
Why is slip of an induction motor an important parameter while choosing it for any application?
In actual operation, rotor speed always lags the magnetic field’s speed, allowing the rotor bars to cut magnetic lines of force and produce useful torque. This speed difference is called slip speed. Slip also increases with load and it is necessary for producing of torque.
Why is an induction motor used for most domestic applications?
Induction motors are used in industrial and domestic appliances because these are rugged in construction requiring hardly any maintenance, that they are comparatively cheap, and require supply only to the stator.
What are the applications of three-phase induction motor?
Applications of 3-Phase Wound-Rotor Induction Motor
They are used for loads that requires speed control. Typical applications of wound rotor or slip ring induction motors are crushers, plunger pumps, cranes & hoists, elevators, compressors and conveyors.
What are the applications of single phase induction motor?
Applications of Single Phase Induction Motor
These motors find use in fans, refrigerators, Air-conditioners, Vacuum cleaners, washing machines, centrifugal pumps, tools, small farming appliances, blowers etc….
What should be taken into consideration when selecting starting methods for AC motors?
The first consideration is the voltage rating of the magnetic wire used in the motor windings. This rating can range from 1000 to 1600 V, with a common value of 1200 V. The greater the distance between the drive and the motor the greater the magnitude of the voltage spikes reaching the motor.
How motor power rating is selected?
Continuous duty and variable load
the duty cycle is closely related to temperature and is generally taken to include the environmental factors also. v The rating of a machine can be determined from heating considerations. v However the motor so selected should be checked for its overload capacity and starting torque.
What are types of induction motor?
Types of Induction Motors
- Split Phase Induction Motor.
- Capacitor Start Induction Motor.
- Capacitor Start and Capacitor Run Induction Motor.
- Shaded Pole Induction Motor.
What are the practical applications of motor and generator?
The examples of usage of compound motors are in Presses, Shears, Conveyors, Elevators, Rolling Mills, Heavy Planners, etc. The small DC machines whose ratings are in fractional kilowatt are mainly used as control device such in techno generators for speed sensing and in servo motors for positioning and tracking.
What application this small motors are mostly used?
The uses of small/mini motors involve in several many applications like designing sample mini motor projects, CD/DVD players, hard drives, fans, pumps, coffee machines, robotic vacuum cleaners, hairdryers, mixers, bread cutters & spindle drives within modifiable or changeable speed applications.
