In order to procure a motor with attached surface-cooling, the type name of the blower unit must be specified as an ordering subitem of the MKDmotor with the blower arrangement desired.If it is specified as an independent ordering item, the blower unit is delivered separately from the motor (i.e. not attached to the latter).⇒ The serially delivered motor holding brake does not suffice to ensure overall personal protection! ⇒ Ensure personal protection by superordinate failsafe measures: ⇒ Block off the hazardous range by means of a safety fence or a safety screen. ⇒ Additionally secure vertical axes to prevent them from falling or descending after having switched off the motor, for instance as follows: – lock the vertical axis mechanically, – provide an external braking / collecting / clamping device, or – ensure proper weight compensation of the axis.
Holding Brakes
Optional. Required for holding the servo axis when the machine is in the de-energized state.The holding brake is operated according to the “electrically releasing” principle. In the de-energized state, a magnetic force acts upon the brake armature disk. This causes the brake to close and to hold the axis. By applying 24 VDC, the permanent magnetic field is compensated by the electrically generated magnetic field: the brake opens.The holding brake is activated by the drive controller. This ensures the proper on and off order in all of the operating states. Note: A premature wear and tear of the holding brake is possible! The holding brake wears after approx. 20.000 motor revolutions in closed state. For that reason, do not use the holding brake as a system brake to stop a moving axis! This is permitted for EMERGENCY STOP situations only. Please observe the instructions on putting the holding brakes into operation described in the chapter entitled “Startup, Operation, and Maintenance”.
Output Shaft and Motor Bearing
Plain shaft The standard design recommended for MKD motors provides a frictionlocked shaft-hub connection without play and excellent running smoothness. Use clamping sets, clamping sleeves or clamping elements to couple the machine elements to be driven. Output shaft with key The optional key according to DIN 6885, Sheet 1, version 08-1968, permits keyed transmission of torques with constant direction, with low requirements for the shaft-hub connection.
