For the nowadays ,the brushless motor are widespread use in the electrical
machinery industry. And the product of restriction on useing AC and DC motor
and consumes energy high, has been unable to satisfy the industry demand the
right now. Develops BLDC control pattern, meets the environment need which
the high efficiency consumes energy lowly. The EC motor for the electronic
phase change control, is the DC brushless motor the new control pattern, the
precise electronic phase change simplification tradition AC rotor pattern,
the utilization permanent magnet also causes the stator winding the
manufacture simple as the motor rotor. The EC motor may used at the AC power
supply , causes the EC motor to be possible to use in the AC environment,
achieved AC to DC the transformation control, and through the adjustment
motor rotational speed, lets the EC motor compare AC or the DC motor energy
conservation approximately 20%~30%. The use environment type is different,
the utilization shuts the control temperature, the pressure as well as the
customer demand choice parameter, uses exterior sensor to provide 0V~5V or
the 0~10V input signal, may maintain the electrical machinery effectively in
the different rotational speed scope the efficiency curve, as a result of EC
motor not synchronized rotational speed limit and AC voltage undulation
influence, therefore may unfold its efficiency curve stably.
The EC motor :
1.EC motor has precise and the smooth phase change
2. Does not have the peak when the power supply started, and the power
dissipation are balance.
3. Green science and technology product, the energy conservation reduces the
carbon.
