Wiring Guidelines
“mototek” motors up to 3kw normally designed for star connection for 415V , 50Hz, 3 Phase supply, but with increasing usage of 230V inverter, these motors are supplied with six terminal to create star or delta connection as required. Motors above 4kw are normally supplied with six terminals for star-delta connections. Motors with six terminals have to be connected in accordance with supply conditions. Verify the connection instruction before putting the motor in operation. With different connections of the motor, it is possible to use the some motor of different voltage supplies (Dual voltage motor)
Star Connection - On a six termination plate, connect U1, V1 and W1 with the link supplied along with the motor and connect three phase supply wires to U2 , V2 and W2 to connect the motor in star connection.
Delta Connection - On a Six termination plate, connect V1-U2, U1-W2 and W1-V2 with the link supplied along with the motor and connect three phase supply wires to U1, V1 and W1 to connect the motor in delta connection.
While changing the connections, ensure that the rated Voltage is maintained on the supply to brake, rectifier or any other type of accessories / equipment which are directly connected to the motor termination.
