Basic design characteristics Fully laminated stator, main poles and interpoles. Compact square frame design. Easy installation of accessories. Large openings in end shields for easy inspection. Stator windings of varnish insulated copper wire. Laminated armature core of high grade insulated electroplate. Large number of cooling ducts in armature provide excellent cooling. Scrambled armature laminations for low torque ripples. Armature windings of varnished copper designed for low commutating stresses and high mechanical strength. Armature is impregnated to ensure high degree of heat transfer....

7 Select motor frame size against voltage, output and speed. For intermediate output, take the nearest higher output listed under the next frame size. For intermediate speed take the next lower speed listed within the output required. The output lists are based on: • Cooling forms IC06/IC17/IC37/IC86W. • The armature circuit resistance listed is for duty warm condition. • The inductance listed is for the armature circuit. • Motor supply from 3-phase fully controlled thyristor. Constant power/constant torque The full field or base speed and maximum speed through field control with constant output...

38 Ordering Fan blower The fan blower can be mounted on top or on either side, at the drive end or at the non-drive end. The location does not affect the output of the motor (except when specified in the tables). The fan can be delivered with a slotted cover, a filter or a flange for an air-duct. On request a pressure switch can be installed on the fan blower and the terminal box can be arranged in 42 different mounting combinations. Pos 25-42: Additional price for blower and terminal box mounted on same side.
