Encoder type BMB-6202-SKF for i-series
Producer: SKF
This encoder consists of two components: a standard-sized bearing with
embedded magnetic encoder. The resolution INC is dependent upon bearing size
and thus dependent on Drum Motor size.
The resolution INC in increments per drum revolution can be calculated as
follows:
INC = p x gear ratio (i)
The gear ratio (i) can be found in the main Drum Motor catalogue.
p = The number of encoder pulses per rotor revolution selected according to the
following table:
1)
On 80i only available with a special shaft diameter of 25 mm.
