A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
The Wimshurst machine or Wimshurst influence machine is an electrostatic generator, a machine for generating high voltages developed between 1880 and 1883 by British inventor James Wimshurst (1832–1903). [citation needed] It has a distinctive appearance with two large contra-rotating discs mounted in a vertical plane, two crossed bars with ...
Electromechanics. A relay is a common electro-mechanical device. Electromechanics[1][2][3][4] combines processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other.
An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric ...
A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnect.

Electric machine. In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. They are electromechanical energy converters: an electric motor converts electricity to mechanical power while an electric generator converts mechanical power to ...

The company was founded in 1895 by John C. Lincoln with an investment of $200 to make electric motors he had designed. [3]The company is headquartered in Euclid, Ohio, and has 44 manufacturing locations, including operations and joint ventures in 19 countries and an international network of distributors and sales offices covering more than 160 countries.
