of synchronous kit motors are magnetically not shielded and permanently
generate a static magnetic field (DC field) even if not activated. This is indica‐
ted by a warning label attached to each package with open permanent mag‐
net components.
If all regulations and safety measures are complied with, synchronous kit mo‐
tors with open permanent magnet components do not cause any inadmissible
hazards. As of a distance of approx. 100 mm to the surface of open perma‐
nent magnet parts, there is practically no effective magnetic attraction of fer‐
romagnetic parts. However, for people with implants, a minimum safety dis‐
tance of 1 meter (1000 mm) is recommended.
Depending on the operating location, transport ways and storage of the ma‐
chine and its components, local regulations and laws apply and have to be
complied with during construction, transport and operation of the machine.
Electromagnetic / magnetic fields! Health
hazard for persons with heart pacemakers,
metal implants or hearing aids! Material dam‐
age.
WARNING
Hazards due to magnetic and electromagnetic fields at live
components or permanent magnets of electric motors.
Persons with active implantable medical devices (AIMD) or
passive metallic implants must keep clear from these motor
components.
The above-specified persons are prohibited from accessing
areas where such drive components are installed and operat‐
ed or access is subject to prior medical consultation.
Keep magnetic data carriers, credit cards, check cards and
identity cards and all ferromagnetic metal parts away from
magnetic fields. Do not wear jewelry, particularly made of fer‐
romagnetic material, during work at magnetic components.
Safety measures for operating
personnel
In the European Community (EU), directive 2004/40/EC specifies minimum
requirements for protection of the safety and health of employees from haz‐
ards due to electromagnetic and magnetic fields. Regulations and guides for
machine manufacturers and machine operators are included in the following
documents:
●
Standard EN 50499 (Germany: DIN EN 50 499, DIN VDE 0808-499)
● Standard EN 50527 (Germany: DIN VDE 0848-3)
● In Germany: Accident prevention regulations BGV/GUV-V B11
This list does not claim to be exhaustive. Machine manufacturers and ma‐
chine operators are required to define the regulations applicable on site and
the occupational health and safety measures to be applied for working in the
area of exposition. The decisive factors are not the electromagnetic proper‐
ties of individual machine components but the effective overall exposition in
electrical, magnetic and electromagnetic fields in the actual working area.
Construction information During construction of the machine, suitable covers and safety equipment for
safe operation must be applied.
●
During construction of the machine, observe applicable standards and
regulations on marking of and access to exposition areas.
● Prevent any access of operating personnel in the motion range of mo‐
tors during operation.
