Each order of a product by Rexroth must be based on the type code. All avail‐
able motor variants are uniquely described by their type code. The individual
characters of the type code (abbrev. column) and their meaning are described
below.
● The chapter "Application notes" includes detailed explana‐
tions for the separate options.
● Before ordering, please check the availability of the separate
options with your Bosch Rexroth sales partner.
MKE, Rexroth designation for servomotors that are suited for the use in poten‐
tially explosive areas.
The motor frame size determines important mechanical motor specifications
and is proportional to the performance variables.
Within a series, the graduation of increasing motor frame length is indicated in
alphabetic order.
In connection with the motor frame size and motor frame length, the winding
codes define the electric motor output data for all Bosch Rexroth motors.
MKE motors are equipped with encoder systems. For the regulation of the mo‐
tor speed or the positioning of the motor, the drive control device must know
the current motor position. The integrated encoder system provides the drive
control device with corresponding signals.
The following options are available:
