EPR
With radial pole arrangement
These circular electro magnets are notable for
their very high holding force. Radial T-slots
can be provided in the pole plates for added
flexibility.

USE
Grinding of circular and ring-shaped workpieces
on carrousel internal and external grinding
machines. Also suitable for turning with form
and position tolerances of 0.01 to 0.02 mm.
- equal pole pitch within
circle range; therefore
very suitable for circular
and ring shaped
workpieces
- for ring-shaped workpieces
the minimum height is
35% of the pole pitch
at the given circle
segment
- also for thin rings
Nominal holding force:
120 N/cm2,
adjustable by control unit with encoded switch

Nominal operating voltage:
24 V DC up to 90 W
110 V DC all sizes

Features
- solid designed pole plate
- radial pole arrangement, especially
suitable for the use of pole raisers.
This is absolutely essential for the runout
of the tool or the grinding wheel at three
side operation.
Therefore available with T-slots (T)
according DIN 650-10H10 on request.
- pole plate wearing limit 8 mm
- suitable for continuous (100%) operation

Scope of supply
- Lifting bolts for transportation on larger models.
- T-slots and pole extensions not included as
standard.
- Terminals for electrical connection in
middle of back side in standard execution.
- Optional with integrated slip ring body for the
bigger diameters.
