IEC VARIABLE SPEED DC MOTORS INTEGRAL HP Technical Description STANDARD MOTOR FEATURES – SUMMARY Refer to GENERAL INFORMATION – page 2 for complete features. Standard guarantees are made on the basis that the motor will operate at an altitude from sea level to 1000 m per IEC 34-1. Refer to Mod. 101 for motors operating at higher altitudes. All machine components such as frame, end plates, bearing caps, shaft, terminal box, etc., are machined on the latest CNC machine tools. This ensures a uniformly high quality standard with very low production tolerances. The motor feet are integral, which...

IEC VARIABLE SPEED DC MOTORS INTEGRAL HP Technical Description MAXIMUM SAFE SPEED DC motors are inherently capable of reaching speeds hazardous to personnel and equipment if improperly connected or misapplied. Operation of a shunt wound or compound wound motor without the shunt field energized at the proper current may cause the motor to reach a dangerous speed. Both the motor instruction manual and the control instruction manual must be followed when the motor is being connected and operated and the work must be performed by qualified personnel. All DC motors of the RPM III series are...
