Flange Mount Motor

Our crane motor are used in crane lifts and cranes. Crane motors are exposed to extreme weather conditions and have high operational requirements. They have to withstand high humidity, salty air and high wind speeds while ensuring a high overload capacity and a wide speed control range. Our crane duty motors are specially designed for service on cranes and hoists. These motors can serve as auxiliary motors in construction sites 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 or stops and reversals. Also rapid acceleration is achieved by high pull out torque or rotor inertia ratio. The crane motors we offer are supplied with EMCO Brakes. Our Crane duty motors are suitable for both three phase and single phase power supply. The motors are rated at 400C ambient temperature.

Application:-

Material handling lifts, hoists, rolling mill and in construction industry

Features:

Ideal for frequent starts and stops and reversing operations

Casting for flange cover and body is made of Alluminium die casting

Terminal box can be rotated in any desired direction

Can be supplied with electromagnetic fail safe AC brakes

Flame proof enclosures

Increased efficiency and more flexibility

Ideal for frequent starts/stops and reversing operations in material handlings, lifts hoists and rolling mills. Motors are suitable for:-

Short time duty (S2)

Intermittent periodic duty (S3)

Intermittent duty with starting (S4)

Intermittent duty with starting and electrical Braking (S5)

Crane duty motors are specially designed for frequent starts/stops & reversing required in cranes & lifts of all types. They can also be used in applications such as material handling, weirs & sluices, auxiliary motors in rolling mills or wherever intermittent drives are required.

Construction:
Castings: Crane duty motors body is made out of aluminium die cast and end shields are made from high quality castings as per IS 210.  All components are machined to correct accuracy & alignment.
Stampings: The stampings are made from low loss high permeability steel.
Terminal Box: Standard location of terminal box.
Winding & Protection: All motors are wound with super enameled dual coat copper wires. This enable motors to be used for inverter applications as well. Features like vacuum pressure impregnation (VPI) & PTC thermistors embedded in stator winding can be provided on request.
Earthing terminals: Two earthing terminals are provided, one in the terminal box & other on the motor body.
Motors with integral brakes:
These motors can be supplied with integral electromagnetic DC fail safe brakes with built in rectifiers .
