Idea:
a single-phase AC motor speed steady speed circuits latest patent. This utility model discloses a stable exchange rate single-phase motor control circuit. Including the control unit. Speed display circuit. Control information input circuit. Speed feedback circuit and Electric Motor implementation of the circuit: the power phase also includes the sampling circuit in the AC power through the acquisition phase signal, after amplification. rectifier. filtered reached control unit. control unit through the operation. certain duty cycle output signal is sent to motor implementation of the circuit to control the motor speed; through the acquisition phase AC power in the signal sent to control unit through the operation, the output signal of a certain duty cycle to control the conduction angle of SCR. This speed control mode allows the controller compact cost is lower than the frequency mode. tremendous market potential
