Rotor Rotation Direction

 We use the left hand rule on electric motors to determine the direction of rotation of the armature conductors. This rule consists of: with the thumb, forefinger and middle of the left hand perpendicular to each other, point the indicator towards the magnetic field flow lines and the middle finger in the direction of the current passing through the conductor RAB STL200W-LED , thus the thumb direction of the driver.

Two forces act to produce a torque by turning the coil clockwise, so the electric motor of a single coil is impractical because it has dead centers and the torque that will be produced is pulsating. Switching is fundamental for a DC motor as it reverts to current in a conductor as it moves under a pole of opposite polarity. In a rectangular coil formed by a single loop parallel to a magnetic field, the direction of current in the left conductor is outward while in the right side conductor is inward. As a result, the driver on the left moves upward with a force F1, and the driver on the right hand side moves down with a force equal to F2
