Philips Norelco is the American brand name for electric shavers and other personal care products made by the Consumer Lifestyle division of Philips. [ 1 ] [ 2 ] For personal care products marketed outside the United States, Palau, Micronesia, and the Marshall Islands, Philips used the Philishave trademark until 2006.
The Philishave shaver was invented by Philips engineer Alexandre Horowitz, who used rotating cutters instead of the reciprocating cutters that had been used in previous electric shavers. The shaver was introduced in 1939, though initial production was limited due to the outbreak of World War II (the production facility in Eindhoven , the ...
An electric shaver (also known as the dry razor, electric razor, or simply shaver) is a razor with an electrically powered rotating or oscillating blade. The electric shaver usually does not require the use of shaving cream, soap, or water. The razor may be powered by a small DC motor, which is either powered by batteries or mains electricity.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
A stepper motor, also known as step motor or stepping motor, [1] is a brushless DC electric motor that rotates in a series of small and discrete angular steps. [2] Stepper motors can be set to any given step position without needing a position sensor for feedback. The step position can be rapidly increased or decreased to create continuous ...
An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
Electric hair clippers work in a similar way as manual ones, but are driven by an electric motor which makes the blades oscillate from side to side. [6] They have gradually displaced manual hair clippers in many countries. Three different motor types are used in clipper production: magnetic, rotary and pivot.
