Energy Efficient Motors

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.

Flame Proof Motors

Another first from CGL : Flame proof motors for Gas group IIC
CGL has enjoyed your confidence for years, whenever there was a need felt for a motor to be used in explosive atmosphere.
Our Standard range of flame proof motor confirms to Energy Efficient level 2 as per IS 12615 (EFF1 optional). This range is suitable for Gas groups I, IIA, IIB as per IS 2148 with temp class T4.
Indian statutory approvals like CMRI, DGMS, CCE, DGFSLI are available for complete range of squirrel cage & slip ring motors.  BASEEFA approval is also available for the complete range making the motor's globally acceptable.
Now to meet the growing need for motors for use in Gas group IIC atmosphere, we have developed a complete range from E80 to E315L frames (0.18 to 200 kW).  This range is duly approved by CMRI Dhanbad

Crane Duty Motors

APPLICATION :
Crompton Greaves 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, weirs and sluices, and lifts of all types. These motors can serve as auxiliary motors in rolling mills or wherever intermittent 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 torque/rotor inertia ratio.
RANGE :
Tables on page nos. 6 to 18 indicate the frame v/s output relationship for slip ring crane duty motors. Tables on page nos. 19 to 27 indicate the frame v/s output relationship for squirrel cage crane duty motors.
MOUNTING :
Squirrel cage crane duty motors are supplied with horizontal foot-mounting. However, motors suitable for vertical foot / flange / face-mounting or any combination of these can be offered when required. Slip ring motors are normally available with foot mounting. Flange mounting can be supplied on specific request.
