In its catalog data sheets maxon specifies the motor data with block commutation (according to «Standard
Specification no. 101», which you can find in the maxon catalog in chapter “Technology short and to the
point”. For detailed information and values consult the data sheets in the
 Appendix as of page 30.
The motor data listed below refer to field-oriented control (FOC) and therefore differ from the catalog data
based on block commutation. In connection with FOC maxon recommends using the «TSX MAG» encoder
module, which can generate both incremental and commutation signals (Hall signals).

[a] The values refer to field-oriented control (FOC).
[b] The nominal voltage is based on the assumptive supply voltage of 48 VDC for a positioning control-
ler with a maximum output voltage of 90% of the supply voltage (0.9 x V
CC
).
