CRANE DUTY MOTORS
 
 
 
 
INTRODUCTION
APPLICATION
"Hindustan" brand crane duty motors are specially designed for frequent starts/stops & reversing required in ther cranes & lifts of all types. They can also be used in application such as --material handling, weirs&sluices, auxilary motors in rolling mills or wherever intermittent drives are required.

CONSTRUCTION :
Castings : "Hindustan " crane duty motors' housings & 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 is on top. However the terminal box on right or left side can be provided on request. The terminal box can rotated in steps of 90 degrees in each position.
  
MOTORS WITH INTEGRAL BRAKES :
These motors can be supplied with integral electromagnetic DC fail safe brakes with built in rectifiers.
 
FLAME PROOF MOTORS :
"Hindustan' crane duty motors are also available with flame proof enclosures.
 
ENQUIRY DETAILS :
When placing enquiry , please furnish following details
• Application details
• Motor power & speed
• Voltage & frequency variations
• Mounting
• No. of start / stop per hour with duty & CDF
• Load GD at motor speed
• Load torque or torque speed curve of driven equipment.
• Duty cycle diagram if other than those described here in.
 
DEFINATIONS :
The terms frequently used in intermittent duty drives are as follows :
1) Duty : Operation of the motor at load including no load & deenergised period to which the motor is subjected including the sequence & duration.
2) Cyclic Duration Factor ( CDF ) : The ratio between the period of loading including starting & electric braking and the duration of the duty cycle expressed as percentage.
3) Starting : The processing of energizing a motor to bring it upto its rated speed from rest.
4) Electric Braking : A system in which a braking action is applied to an electric motor by causing it to act as a generator.
5) Rwegenerative Braking : A system of electric braking in which energy is returned to the supply system.
6) D.C. Injection Braking : A form of braking of an induction motor in which a seperate DC supply is used to magnetise the motor.
7) Plugging : A form of braking of an induction motor obtained by reversing thwe phase sequence of its any two lines.
