Big Motor was founded in 1976 by Hiroyuki Kaneshige as Kaneshige Auto Center in Iwakuni, Yamaguchi Prefecture.In 1980, the company was renamed to Big Motor, and began opening stores elsewhere in Yamaguchi Prefecture, including Shimonoseki in 1984, Hōfu in 1985, and Kudamatsu in 1995.
An induction motor resembles a rotating transformer, because the stator (stationary part) is essentially the primary side of the transformer and the rotor (rotating part) is the secondary side. Polyphase induction motors are widely used in industry. Large 4,500 hp AC induction motor
Small synchronous motor with integral stepdown gear from a microwave oven. A synchronous electric motor is an AC electric motor in which, at steady state, [1] the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integer number of AC cycles.
A simple DC motor has a stationary set of magnets in the stator and an armature with one or more windings of insulated wire wrapped around a soft iron core that concentrates the magnetic field. The windings usually have multiple turns around the core, and in large motors there can be several parallel current paths.
The Large Motor Division, once headquartered in Buffalo, NY, entered a joint venture with Taiwan Electric Co. (TECO) in the 1970s and today operates as TECO-Westinghouse. [26] Much of Westinghouse's higher voltage power equipment was sold to ABB in 1989 and renamed the ABB Power T&D Company. [27]
The motor size constant and motor velocity constant (, alternatively called the back EMF constant) are values used to describe characteristics of electrical motors. Motor constant [ edit ]
