HIGH EFFICIENCY MOTORS

  
High Efficiency Motors
 
 
 
 
INTRODUCTION

RANGE:
"Hindustan" motors are available from frame sizes 56 to 315 in 2, 4, 6 & 8 pole designs. The motors are suitable for continuous (S1) duty with ambient temperature of 450C & Site altitudes of upto 1000 meters above mean sea level.
 
VOLTAGE & FREQUENCY :
Motors are designed for 3 phase, 415 + 10 % & 50 Hz + 5 % with combined variation of 10 % Any other voltage & / or frequency is available on request.
 
STANDARDS :
Motors conforms to IS:325, IEC 34, Part 1 & BS 4999 for electrical specifications & IS:1231 for mechanical dimensions.
 
TERMINAL BOX POSITION :
Standard location of the terminal box is on top. However for frame sizes 90 to 315, the terminal box on right or left side can be provided on request. The terminal box can be rotated in steps of 900 in each position.
 
PROTECTION :
The motors are designed with class F insulation & IP55 degree of protection as per IS:4691 & IEC 34, Part 5.
 
CONNECTION :
Motors upto 2 HP are star connected with 3 leads & from 3 HP onwards they are delta connected with 6 leads.
 

TORQUE CHARACTERISTICS :
The nominal torque of the motor TN' is the torque developed by the motor at rated speed n, while delivering the rated power P. The relationship between these three parameters is

                               TN' = 9550 x [P/n] (Nm)

                            where P = Power (kW)
                                       n = motor speed (rpm)

               Alternatively, torque  TN' in kgm can be given as
                                        TN' = 974 x [P/n] (kgm)

 
MOMENT OF INERTIA :
The moment of inertia J is given in kgm2. The moment of inertia is numerically equial to 1/4 GD2. The load moment of inertial JL of the driven machines at rated speed nL when refered to motor speed n rpm is given by
J = JL [nL/n]2
 
NOISE :
Motors are designed for low noise levels in accordance with IS:12065
 
COOLING :
Type of cooling is IC 0141 in accordance with IS:6362. All motors are fitted with external bi-directional cooling fan.
