Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Dynamic and static modes of implicit-pole collector-free DC motor with symmetric rotor excitation KOKHREIDZE D.K. The complex equations of transient processes on average values of variables of implicit-pole collector-free motor are derived. The stator has a three-phase motor radial winding. The rotor is implicit-pole with symmetric excitation. The thyristor switch is assembled on a three-phase bridge circuit with pick-off diodes. The frequency of switching phases of stator winding and rotor speed are synchronized with the rotor position sensor. The equations of motor for d and q components of the current in a form suitable for computer programming are written down. The analytical expressions of the transient currents in the case of a constant rotational speed of rotor are obtained. The steady motor behavior is considered. The corresponding expressions of stator and rotor current, electromagnetic torque and other static characteristics of the motor are given. Keywords: collector-free motor, implicit-pole rotor, pick-off diode, commutating capacitor, electromagnetic torque, mechanical characteristics, rotor position sensor.
