Abstract
A kitchen appliance has a base, a driven mechanism rotatable relative to the base, and an electric motor with a stator and a rotor for driving the driven mechanism. The stator comprises a stator core with two primary stator poles with stator windings wound there on and two auxiliary stator poles. The stator windings are configured in such a way that primary magnetic poles with the same polarity are formed at the primary poles and induced magnetic poles with the same polarity which is opposite to the polarity of the primary magnetic poles are formed at the auxiliary poles when the motor is electrified.
Claims11
A kitchen appliance comprising:
- a base;
- a driven mechanism rotatable relative to the base;
- and
- an electric motor with a stator and a rotor for driving the driven mechanism;
- wherein the stator comprises a stator core with two pairs of stator poles and stator windings wound about at least one pair of stator poles, and two pairs of magnetic poles with opposite polarity are alternatively formed at the two pairs of stator poles when the motor is electrified.
A kitchen appliance comprising:
- a base;
- a driven mechanism rotatable relative to the base;
- and
- an electric motor with a stator and a rotor for driving the driven mechanism;
- wherein the stator comprises a stator core having a yoke which comprises at least two first sections, each with a primary pole extended there from and at least two second sections each with an auxiliary pole extended there from, the at least two primary poles and the at least two auxiliary poles are alternately arranged in the circumferential direction of the stator core, and the at least two primary poles have stator windings wound thereon;
- and
- wherein the stator windings are configured in such a way that primary magnetic poles with the same polarity are formed at the primary poles and induced magnetic poles with the same polarity which is opposite to the polarity of the primary magnetic poles are formed at the auxiliary poles when the motor is electrified.
