VACUUM AP D
APPENDIX D
The Tecnotion vacuum motors come with stainless steel coil housing and
PTFE flying lead wires to reduce outgassing. The magnet yokes are specifi-
cally designed for vacuum chamber compatibility e.g. by the application of
nickel coated magnets.
All warnings and requirements as described in the ironless manual also ap-
ply to vacuum motors. This appendix only highlights the difference from
standard ironless motors.
CE certification/Machine Directive for vacuum motors
Tecnotion B.V. declares that the UMV and ULV linear motors mentioned in
this Installation manual are destined to be incorporated in or combined
with other machines and are only in compliance with the Machine Direc-
tive (98/37/EC) for bus voltages below 75Vdc.
For higher bus voltages specific measures need to be taken to provide safe
operation according to the Low voltage directive (2014/35/EU).
The extra measures needed to also comply for higher voltages are split in
three different groups: <75Vdc, <250Vdc, <300Vdc
COMPLIANCE WITH MACHINE DIRECTIVE FOR <75VDC
Since all wires only have a single isolation and no shielding extra protection
might be necessary for the application and is definitely advisable.
Because the vacuum motors normally operate in a (metal) vacuum cham-
ber the chamber itself can be used as extra protective measurement. A
grounded metal vacuum chamber will keep all EMC distortion inside the
chamber and makes it impossible to touch the coil. This protection is only
sufficient when it is combined with a fail save that when the chamber is
opened all power to the coil is disconnected automatically.
The vacuum chamber wall is advised to be connected to a physical earth to
prevent possible shock.
The UMV and ULV Vacuum motors are not supplied with an
internal strain relief. Appropriate strain relief of the power and
sensor wires need to be provided externally.
UMV and ULV power and sensor cables only have single isolation.
Without further protective measures they may only be used
below 75Vdc.
UMV and ULV coils do not have a PE wire. Appropriate grounding
of the stainless steel housing with respect to the used bus voltage
and application needs to be implemented by the customer.
