Title: Operating circuit for preventing reverse rotation
Inventor: TAGA AKIYOSHI
IPC: F04B49/10
Filed: 1985-07-10
Abstract: PURPOSE:To judge the operation or non-operation of a plugging relay simply by working an electromagnetic contactor for manually operating a motor when a power supply is antiphase-connected and the motor is not worked. CONSTITUTION:When a time limit relay 8 is operated, an electromagnetic contactor 2 for manually working a motor is conducted, thus supplying a plugging relay 10 with a power supply. When the power supply is brought to the state of a positive phase, a contact for the plugging relay 10 is closed and an electromagnetic contactor 1 for operating the motor is conducted, and the motor is operated manually. When the time passes and a time limit relay 9 is worked, conduction to the electromagnetic contactor 2 for manually operating the motor is interrupted, and an electromagnetic contactor 3 for DELTA-operating the motor is conducted. The supply of the power supply to the plugging relay 10 is also intercepted at that time. When the motor is not operated by the plugging relay 10, the non-operation of the motor is determined at a glance because a coil for the electromagnetic contactor for manually working the motor is conducted.
