Which one is the Enclave motor relay?
1 Answers
The Enclave motor relay is labeled with its English abbreviation inside the fuse box. Working principle of the relay: The coil of the starting relay is connected in series with the running winding of the compressor motor. During motor startup and operation, the operating current passes through the relay coil, while the control contacts are connected in series with the starting winding, controlling its closure and disconnection. The control contacts of the relay are normally open. When power is first applied, current flows only through the relay coil and the running winding. Since the rotor is stationary, the starting current is very high, causing the relay coil to attract the armature upward, closing the moving and stationary contacts and connecting the starting winding, which allows the compressor to begin rotating. As the speed increases, the current decreases, and the armature falls back by its own weight, opening the contacts and completing the starting process. Function of the starting relay: It assists the motor in starting and automatically disconnects the auxiliary winding after startup to prevent burning out the auxiliary winding coil. When the motor's running winding is energized and the startup phase transitions to normal operation, the starting relay cuts off the power to the starting winding.
