Active implant malfunctions due to permanent-magnet fields
Even when switched off, electric motors with permanent magnets represent a potential risk
for persons with heart pacemakers or implants if they are close to converters/motors.
• If you have a heart pacemaker or implant, maintain the minimum distance specified in
• When transporting or storing permanent-magnet motors always use the original packing
• Clearly mark the storage locations with the appropriate warning labels.
• IATA regulations must be observed when transported by air.
Injury caused by moving or ejected parts
Contact with moving motor parts or drive output elements and the ejection of loose motor
parts (e.g. feather keys) out of the motor enclosure can result in severe injury or death.
• Remove any loose parts or secure them so that they cannot be flung out.
• Do not touch any moving parts.
• Safeguard all moving parts using the appropriate safety guards.
Fire due to inadequate cooling
Inadequate cooling can cause the motor to overheat, resulting in death or severe injury as a
result of smoke and fire. This can also result in increased failures and reduced service lives
of motors.
• Comply with the specified cooling requirements for the motor.
Fire due to incorrect operation of the motor
When incorrectly operated and in the case of a fault, the motor can overheat resulting in fire
and smoke. This can result in severe injury or death. Further, excessively high tempera-
tures destroy motor components and result in increased failures as well as shorter service
lives of motors.
• Operate the motor according to the relevant specifications.
• Only operate the motors in conjunction with effective temperature monitoring.
• Immediately switch off the motor if excessively high temperatures occur.
