Convert electrical energy into mechanical energy (this is called
motor); or the mechanical energy into electrical energy (this is called the
generator); or to one form of energy into another form of energy (this is
called the transformer ), etc. All of these energy conversion can be achieved
in such a device referred to the motor.
The basic principle of the motor is the application of the two laws:
the Faraday's law of electromagnetic induction and Ohm's law, following the
same law of energy conservation.
Motors have AC motors, DC motors and AC /DC motors. AC motor is
divided into induction motor, synchronous motor.
Our company Ningbo Jant electrical appliance co Ltd produce a shaded
pole motor that is an induction motor, stepper motor is a synchronous motor,
also known as a pulse motor, series motor can be designed as AC and DC motors.
Generally refers to the so-called micro-motor input power 1000W
motor below, while the input power is less than 750W micro-motor is also known
as fractional horsepower motors.
We produce a shaded pole motor is a single-phase induction motor
drives a micro, its structure is extremely simple, generally salient pole
stator windings of the primary winding is concentrated, and the surface of each
magnetic pole has opened a small groove, which put short inlay ring (or shaded
pole coil) as the secondary winding, and its function is to short-circuit loop
of the magnetic force of the covering phase, thereby forming a magnetic field
generating ellipse orientation starting torque, the motor start. This motor has
a simple structure, convenient and suitable for mass production and low cost
advantages, but also running, low noise, no radio interference.
The disadvantage is poor operating performance and starting performance,
efficiency and low power factor. It is generally used to load or light load
starting small-capacity applications, such as electric fans, electric fans and
Instrument model and other products.
