The Dimension Sheet and Performance Data Sections contain...

IEC VARIABLE SPEED DC MOTORS INTEGRAL HP Standard Motor Features the windings at working temperature. (Note that the variation in speed can be above and below rated speed.) kW per 1000 r/min Base Speed Tolerance Not less than 2.5 but below 10 BEARINGS Standard IEC DC motors utilize ball bearings. These bearings and their internal clearances have been especially selected based on load carrying ability, thermal stresses and speed range consistent with ample bearing life. Roller bearings are used for belted duty on frames UGK180-UGK280 per the Modification section. The “U” prefix indicates...

IEC VARIABLE SPEED DC MOTORS INTEGRAL HP Standard Motor Features LUBRICATION IEC RPM III DC motors have the Patented PLS/Positive Lubrication System developed and tested by Baldor Electric to provide positive motor bearing protection. Open bearing design allows the lubricant to remove heat from the bearing. Standard grease may be used in ambients down to –25°C. MOUNTING Foot and flange mounting in accordance with IEC standards. Motors will operate successfully mounted on the floor, wall or ceiling and with the shaft at any angle from horizontal to vertical. Hand-hole covers can be...

IEC VARIABLE SPEED DC MOTORS INTEGRAL HP Standard Motor Features TACHOMETER MOUNTING IEC RPM III frames GK132 through GK250 have as a standard feature a provision for mounting an integral AC or DC tachometer. TEST-STANDARD Each motor is given a routine test to determine that it is free from electrical or mechanical defects and to provide assurance that it meets design specifications. This test consists of: (Test data is not supplied to customer without additional charges.) Neutral check Winding resistance Commutation check High potential test No-load test at base speed and maximum field...

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...
