An electric motor utilises the magnetic effect of current. It works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on the coil which rotates it continuously.

The applications of electrical motor include the following. The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.

Electric motor: An electric motor is a device which converts the electrical energy into the mechanical energy. Principle: An electric motor (dc motor) works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field.

The working principle of the electric motor mainly depends on the interaction of magnetic and electric field. The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.

Every electric motor has two essential parts: one stationary, and one that rotates. The stationary part is the stator. Though configurations vary, the stator is most often a permanent magnet or row of magnets lining the edge of the motor casing, which is usually a round plastic drum.

Motors are used in a wide range of applications, such as fans, power tools, appliances, electric vehicles, and hybrid cars.

Types of Electric Motors

• 1). DC Shunt Motor.
• 2). Separately Excited Motor.
• 3). DC Series Motor.
• 4). PMDC Motor.
• 5). DC Compound Motor.
• 1). Synchronous Motor.
• 2). Induction Motor.
• 1). Stepper Motor.

armature core length L are known as the main dimensions of a rotating machine. Total Electric Loading: the total number of ampere conductors around the armature (or stator) periphery is called the total electric loading.

The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.

The main traction motor of the 8000-series single trolleybuses under study is an asynchronous machine of 210 kW rated power; from the perspective of limiting the trolleybus electric energy consumption, the focus is on investigating the regenerative energy saving potential and the efficiency of the machine driving …

The first electric train ran in India with the inauguration of services between Bombay VT and Kurla Harbour on 3rd Feb 1925 on ex-GIP Railway system.

Hence basic elements of an electric drive is electric motor and control system. constant power drive. constant torque drive. variable power drive.

Scotsman Robert Anderson is credited with inventing the first electric car some time between 1832 and 1839. And around 1834 or 1835, American Thomas Davenport is also credited with building the first electric car.

Brushless DC Motors BLDC motors have traction characteristics like high starting torque, high efficiency around 95-98%, etc. BLDC motors are suitable for high power density design approach. The BLDC motors are the most preferred motors for the electric vehicle application due to its traction characteristics.

Electric cars have some disadvantages, such as: Reliance on rare-earth elements such as neodymium, lanthanum, terbium, and dysprosium, and other critical metals such as lithium and cobalt, though the quantity of rare metals used differs per car.
