Hi,
I'd like to design a circuit able to control the torque and the direction of a universal motor.
I know the direction isn't supposed to be changed but the motor will run at very low speeds or even motionless.
To avoid overcurrent, i'll bridle it to 110v even if the mains will be 220v AC 50Hz.
I connect the two windings (armature and rotor) in series, and to reverse the direction, I must reverse the curent passing through one winding and not both. (H-bridge ?)
How would you do this ? Triacs, thyristors, mosfets, IGBTs ?
