As we know, an electric motor plays a vital role in every sector of the industry, and also in a wide range of applications. There are a variety of types of electric motors are available in the market. The selection of these motors can be done based on the operation and voltage and applications.

Efficient use of motors is always important, but there are many other things to consider when specifying an electric motor. Mechanical and environmental considerations are on the list, as is the application and operation. All of these factors are important, but the application is where the selection process should start. The application defines the motor load, speed, acceleration, deceleration and duty cycle of the motor. This all feeds into the horsepower and torque requirements.

Different Types of Electric Motors

AC motors are highly flexible in many features including speed control VSD - Variable Speed Drives and have a much larger installed base compared to DC motors, some of the key advantages are:. The current trend for VSD is to add more features and programmable logic control PLC functionality, which add advantages but require greater technical expertise during maintenance. In this type of motor, the rotation of the rotor is synchronized with the frequency of the supply current and the speed remains constant under varying loads, so is ideal for driving equipment at a constant speed and are used in high precision positioning devices like robots, instrumentation, machines and process control.

This type of motor uses electromagnetic induction from the magnetic field of the stator winding to produce an electric current in the rotor and hence Torque. These are the most common type of AC motor and are important to industry due to their load capacity, with Single-Phase induction motors being used mainly for smaller loads, for example in household appliances whereas, Three-Phase induction motors are used more in industrial applications including compressors, pumps, conveyor systems and lifting gear.

There are many aspects to consider when selecting an industrial motor, such as application, operational, mechanical, and environmental issues. Knowing which one to use depends on the industrial application and if there are any special needs required. A constant or variable torque and horsepower will be required for the industrial motor depending on the type of load the motor is driving. Requirements for controlling motor speed and position also need to be considered. Variable horsepower and constant torque applications include conveyors, cranes, and gear-type pumps.

Different types of motors and their use

Premium Membership. Learn from experienced power engineers. Almost all modern industrial and commercial undertakings employ electric drive in preference to mechanical drive because it possesses the following advantages :. However, the above two disadvantages can be overcome by installing diesel-driven DC generators and turbine-driven 3-phase alternators which can be used either in the absence of or on the failure of normal electric supply. 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. It has high starting torque, large overload capacity and a nearly constant speed. It has high starting torque and large overload capacity.

Most complex drives. (servos, industrial robots, linear motors) require additional position control. Applications requiring the motor to operate with a specified torque.


Selecting Motors for Industrial Applications

 Могу я для вас что-нибудь сделать. Клушар задумался, польщенный оказанным вниманием. - Если честно… - Он вытянул шею и подвигал головой влево и вправо.

 Разумеется, не можете. Его же не существует. - Коммандер, я должна… - попробовала вставить слово Сьюзан. И снова Стратмор нетерпеливым взмахом руки заставил ее замолчать.

Три. Эта последняя цифра достигла Севильи в доли секунды. Три… три… Беккера словно еще раз ударило пулей, выпущенной из пистолета. Мир опять замер. Три… три… три… 238 минус 235.

Он писал письма, отправлял их анонимному провайдеру, а несколько часов спустя этот провайдер присылал эти письма ему самому.

All About Motors

 И у тебя нет кредитной карточки. - Есть, но отец ее заблокировал. Он думает, что я балуюсь наркотиками.

Солнечные лучи, проходя сквозь этот экран, покрывали стены нежным кружевным узором. Крошечные частички пыли, пленницы мощной системы деионизации купола, простодушно устремлялись вверх широкой спиралью. Наклонные стены помещения, образуя вверху широкую арку, на уровне глаз были практически вертикальными. Затем они приобретали как бы полупрозрачность, завершаясь у пола непроницаемой чернотой - посверкивающей черной глазурью кафеля, отливавшей жутковатым сиянием, создававшим какое-то тревожное ощущение прозрачности пола.


Shunt DC motor: The rotor and stator windings are connected in parallel. 2. Sparately Excited smaller in size. Disadv: only used for low torque applications.

special motors, leaving the majority of applications in the hands manual) control over the full range from 0 to 12 V, but the snag is that power is wasted in the variable-voltage d.c. supply needed for speed control of an industrial. d.c. motor.

Motors are mechanical or electro-mechanical devices that convert energy into motion.
