Crompton Greaves has now developed a complete family of high efficiency motors confirming to Eff level 1 standards of IEEMA : 19-2000 and other applicable standards in Europe and rest of the world.
These motors are available in TEFC construction for use in safe areas and also in flameproof enclosure for use in Hazardous areas.
SPECIAL DESIGN FEATURES :Higher efficiencies are achieved by following special features :
Low loss special grade of thinner laminations. This reduces the Iron loss even at partial loads.
Thicker conductors and more copper contents reduce copper loss due to lower resistance.
Longer core length, reduced and uniform air gap between stator and rotor to reduce stray losses .
Special design of fan and fan cover to reduce windage losses.

Prabal series squirrel cage/slip ring Crane duty motors are specially designed for service on cranes and hoists. They can also be used for similar applications such as material handling equipments, and cranes of all types. These motors can serve as auxiliary motors in rolling mills or wherever intermittent duty drives are required.
These are duty type rated motors developing high starting torque with low starting current. The motors are suitable for frequent starts/ stops and reversals. Also rapid acceleration is achieved by high pull out torquelrotor inertia ratio.
Crane duty motors are used for following applications in majority: Cranes & hoists: long travel drive, cross travel drive, main hoist, auxiliary hoist. Material handling equipments: various conveyors Lifts Rolling mills
Manufacturing range for cast iron slip ring crane duty motors is from 112 to 400 frame. The same for squirrel cage motors in cast iron enclosure is from 80-400 & in aluminium enclosure is from 63-160.
Squirrel cage crane duty motors are supplied with horizontal foot- mounting. However, motors suitable for foot / flange / face mounting or any combination of these with vertical or horizontal orientation can be offered when required. Slip ring motors are normally available with foot mounting Flange mounting can be supplied on specific request.
Crane duty motors are suitable for 3 phase supply and can be wound for any single voltage from 220 to 650 volts and frequencies from 50 Hz or 60 Hz. The rotor voltage is committed for stator supply of 415 V, 50 HZ.For other supply conditions, Rv to be confirmed from CG.
The motors are rated at 45C ambient temperature. For temperatures, other than 45C, a deration factor has to be applied as indicated below.
