Induction Motor is
one of the most widely used motor Induction Motor rotor speed is always
slightly lower than therotating magnetic field of the synchronous
speed. Induction Motor is an AC motor, the load speed and frequency
ofthe received power ratio is not constant relationship. Alsochanges
with the size of the load. The greater the load torque,rotor speed, the
lower.
Asynchronous motor including
induction motors, double-fed asynchronous motors and AC
commutatormotor. The most widely used induction motor, not misleading
orconfusing in the case, generally known as the induction motorinduction
motor.
Motor power supply according to work by type: can be divided intoDC and AC motor.
Single Phase Motors is
one of AC motors. Single-phase capacitor motor has two windings,
namely, the start winding and running winding. Difference between the
twowindings in space 90 degrees. In the start winding in series with
alarger capacity of the capacitor, when the start winding and runwinding
through the single-phase AC, due to the role of thecapacitor start
winding current at the time than the run windingcurrent leads the
90-degree angle, first to reach the maximumvalue. In time and space to
form two identical pulsed magnetic field, so that the air gap between
stator and rotor of a rotating magnetic field generated in the rotating
magnetic field, theinduced current in the rotor, the current interaction
with the rotating magnetic field produced electromagnetic torque, the
motor spinup.
In
recent years, brushless motors as the rapid development of the field in
the model as a driving force. As the output and pricereasons, the past
few years, more use of brushless motors in high-end aviation model,
since the rapid development ofmachining technology, brushless motor
production costs of many,and it is currently entering the field at all
levels of the model, fromelectric cars to electric remote control boat
remote control to theelectric model airplanes, everywhere.
Brushless motor is
compared to the brush motor has many advantages. Brushless motors
without a brush, greatly reduced running friction,smooth operation,
noise will be much lower, the advantage ofstability for the model run is
a huge suppor.In addition to brushless motor to the brush, the most
immediatechange is not a brush spark generated when the motor is
running, thus greatly reducing the spark on the remote control
radiointerference.
