Encoder type BMB-6202 & 6205 SKF for the i-series
Manufacturer: SKF
The encoder consists of two components: A standard bearing with built-in magnetic encoder
and a corresponding load resistance whose size varies depending on the operating voltage.
The load resistance is not part of the scope of supply.
The resolution INC is determined by the size of the bearing and, therefore, by the motor frame
size.
The resolution INC in increments per drum revolution is calculated as follows:
INC = p x gear ratio (i)
The gear ratio (i) is listed in the drum motors main catalog and can be requested from Interroll.
p = number of encoder pulses per rotor revolution selected based on the following table:
