1. Product Description
Rib cooled motors, type HXR 560
HXR rib cooled motors have a rugged cast iron frame. They are totally enclosed fan cooled motors with IC411 cooling and IP55 protection as standard. The motors are also available with IC416 cooling and optional IP66 protection.
HXR motors cover the output range up to 2,250 kW, and they are available in shaft height 560. The motors can be mounted horizontally or vertically.
For HXR motors this catalog shows the technical data at 50 Hz only, but the motors are operating at both 50 Hz and 60 Hz, with synchronous speed from 500 to 3600 rpm.
2. Mounting arrangements
Standard mounting arrangements for AXR motors
3. Enclosure and cooling
Standard combinations
IC411 / IP55
HXR motors have an external shaft mounted fan that uses the surrounding air for cooling.
The motors are protected against dust and water jets. The operating principle of these motors is shown in diagram 27 below.
IC416 / IP55
HXR motors are available with IC416 cooling.
An additional motor drives the cooling fan to produce the cooling required for low speed applications, especially in cases where the motor is fed via a variable speed drive.
Protection rating IP55
• Protection against dust: as in other dust- protected motors, some dust can enter but not in sufficient quantities to interfere with the motor's operation.
• Protection against water jets: water projected by a nozzle against the motor from any direction has no harmful effect.
Protection rating IP66
HXR motors are available with protection ratings up to IP66.
• Protection against dust: the enclosure is completely dust tight.
• Protection against water jets: water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction has no harmful effect.
Cooling method (IC411)
• Frame surface cooled: The primary coolant is circulated in a closed circuit in the motor and gives its heat through the external surface of the motor (in addition to the heat transfer via the stator core and other heat conducting parts) to the final coolant which is the surrounding medium. The surface may be plain or ribbed, with or without an outer shell to improve the heat transfer.
• Self circulation: The coolant is moved dependent on the rotational speed of the main motor either by action of the rotor alone or by means of a component designed for this purpose and mounted directly on the rotor of the main motor, or by a fan or pump unit mechanically driven by the rotor or the main motor.
