A high performance electric pulse motor without a collector, with an electronic control circuit, capable of performing either with direct current or with alternating current. The motor includes a magnetic circuit at its stator including a pair of stator polar pieces, an induction coil at each polar piece, and a rotor between the polar pieces. The rotor has at least a pair of radial extensions in opposition for each pair of polar pieces in the stator and, attached to the rotor's axis, means opaque to light having a window allowing free passage of light. The motor further includes a permanent light source and a photo resistor.
