The Heavy Duty Motors that we offer are specially designed for lifts for smooth starting & silent operation. Motor gives high starting torque & low starting current. Ribs are Provided for efficient cooling. Rotor is of double cage copper bars & dynamically balanced. Sleeve bearings are provided with self circulating oil system with oil seals. Oil recommended is Enklow 320 Hindustan Petroleum. Motor are supplied without oil. Fill Oil Before Use up to half level in indicator in motor off position.

The Horse power of the motor to be used should be taken as input horse power to be transmitted.
Brake torque should be greater than motor starting torque.
Alternative approximate method of determining size of unit.
The unbalanced torque = unbalanced load x lift sheave radius
This torque can then be compared with unbalanced torque ratings given in table.
If this method is used the following information should be given.
o Motor H.P. & Speed.
o Brake torque.
o Gear Ratio.
