Rexroth, Indramat, Bosch's MAC Permanent Magnet Motors are designed for high-precision servo applications in industries such as woodworking and metalworking, as well as production machines in the automotive industry. These motors are typically used for torque direction and control circuit conditioning. The motor's rotor position controls the current flow to the three stator windings, aligning the stator current with the rotor's magnetic flux. A current controller linked to a directional current controller regulates the motor current, allowing for precise control over all three stator windings.
