Repulsion start induction motor. Winding connected to the commutator and c a short circuited set of two brushes. This type of motor is used for such applications as large air compressors refrigeration equipment and large hoists and is particularly useful in locations where low line voltage is a problem. Some older operating units may be found with this type of motor still in use.
A repulsion induction motor has a good and a fairly good b. In repulsion motors the stator windings are connected directly to the ac power supply and the rotor is connected to a commutator and brush assembly similar to that of a direct current dc motor. It works on the combined principle of repulsion and induction.
This is a class of motor that overcomes the induction motors low starting torque and incorporates the large starting torque while loosing the noise an. As soon as the motor is started the squirrel cage winding is practically inactive for a small period of time due to high reluctance. The biggest advantage in such type of motors is that they dont need a separate centrifugal short circuit system as in repulsion start induction run motors.
Repulsion motors are classified under single phase motors. A large cast iron 12 jaw wood planer powered by a repulsion start induction run motor. It consists of a stator winding b two rotor windings.
This type of motor is no longer used in the refrigeration industry. Skip to main content. A repulsion motor has a high starting torque and its speed rapidly decreases with c.
The inner winding is a squirrel cage winding with rotor bars permanently short circuited while outer winding is a repulsion or commutator winding similar to a dc. The repulsion induction motor has a single phase stator winding as a repulsion start induction motor has but it has two separate and independent windings on rotor in common slots. The centrifugal short circuiting device on a repulsion start induction run motor operates at approximately.
One squirrel cage and the other usual dc. Repulsion startinduction run motor.
