OPERATION AND MAINTENANCE MANUAL

MAC QM MOTORS

PAGE: 29

CODE: CTT42 EDITION: 01 RELEASE: JULY 2016

Subject to technical changes without prior notice

3.7.6

Anti-condensation heaters

As an option (on request), one or two heating elements can be installed on the winding heads to prevent condensation on the

motor windings when the motor is to be installed at a site with high relative humidity (> 85%).

The standard VASCAT type is 100 W 230 VAC.

3.7.7

Forced ventilation

MAC QM motors are IC17 air cooled type so they require an external ducted forced ventilation system (not included in the

standard versión). Other mounting options are possible on request.

3.8

Accessories

3.8.1

Calibration arm and load-cell mounting provision

The standard version of the MAC QM motors includes machined pads for calibration arm and load-cell mounting.
