Polyphase motors can be either two-stage or a few-stage motors. They perform like solitary-section induction motors, but the two single-period and polyphase motors operate on a rotating magnetic discipline. Their rotating magnetic fields are generated by two- or three-period currents passing via two or more sets of coils. The rotating magnetic subject produces torque. Polyphase motors are utilized in purposes that call for higher electricity, this kind of as the electricity drive of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
AC motors and gear motors incorporate solitary-phase motors for one-section AC power and a few-section motors for three-period AC electrical power. A solitary-period motor merely demands to be related to a solitary-stage power offer by means of the provided capacitors to operate. 3-phase motors do not need capacitors. You basically link the motor straight to the three-stage AC electricity source. Dongfang Electric gives a broad variety of AC motors and gear motors Consistent or variable speed AC motors are obtainable with one or a few-section equipment and electromagnetic braking possibilities
