Three-phase synchronous motor English
Danger on physical contact:
Make sure that the electric motor has come to a standstill and is secured against
accidental restarting before you touch it.
Only touch the output shaft when it is de-energized and the motor has come to a
standstill. Otherwise, there is a risk due to the rotating rotor.
Danger of burns! Never touch the motor housing when the motor is running at rated
load. Motor surfaces can reach temperatures in excess of 70°C.
4.2 Checks prior to commissioning
• The drive is free of damage and is not located within the danger zone of other equipment
• The motor is correctly aligned and fastened. All screwed connections are correctly tightened.
• All the appropriate safety devices (mechanical, thermal and electrical) are mounted.
• The motor connections have been made correctly.
• The wires are not in contact with the surface of the motor.
• The protective ground has been implemented correctly and its function checked.
• The drive does not lock (release brake, if present).
• Emergency stop functions have been checked.
4.3 Commissioning, operation
Note on brake function (if present):
The brake has been designed to serve as a holding brake with emergency stop
function (power failure, emergency stop).
It must not be used as an operating brake.
Commissioning must only be carried out by qualified personnel.
Please refer to the commissioning instructions for the converter.
Checks during commissioning:
• Release brake if applicable.
• Has the function of all motor modules (e.g., brake, encoder, fan, etc.) been checked and are
they being used in appropriate conditions?
• Have all electrical and other connections been made correctly and tightened? (Please observe
wiring diagrams, see Appendix)
• Have all protection measures that eliminate the possibility of contact with live parts, hot
surfaces, rotating and moving parts, and modules been observed and are these measures fully
functional?
• Have all output elements been mounted and adjusted in accordance with the manufacturer's
instructions?
• Are measures in place to ensure that the max. permissible speed n
max
of the motor cannot be
exceeded? The max. permissible speed n
max
is the highest permitted operating speed for short-
time duty.
Checks during operation:
• Watch out for unusual noises.
• If scraping, scratching, grinding or other noises occur, stop the drive immediately and locate
the cause.
• Check the motor surface and connection cables for dirt, e.g., layers of dust, oil deposits,
dampness, etc.
• Check the maintenance intervals.
