Technical data

MHD Sychronous motors MHD Type Code 4-3

DOK-MOTOR*-MHD********-PR05-EN-P

4. Winding Code

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.

The type code specifies all possible winding codes, which are available

for a motor frame size / length.

Motor frame size / length Available winding codes

MHD112B 024, 035, 048, 058

Fig. 4-4: Winding code example

In chapters 6 to 13, the technical data and the speed-torque curves are

specified for all motors.

5. Motor encoder

MHD motors are equipped with an integrated encoder system (motor

feedback). To control the motor speed and/or to position the motor, the

drive controller requires information on the current motor position.

To achieve this, the integrated encoder system (motor encoder) makes

the appropriate signals available to the drive controller.

The following options are available:

Option Type Type of position detection

N Digital servo feedback (HSF) Relative

P Digital servo feedback (HSF with

integrated multiturn absolute

encoder

Absolute

(more than 4096 revolutions)

6. Output Shaft

To connect the machine elements to be driven to the motor shafts, the

following options are available for MHD motors.

Option Design Detail

G Plain shaft

P Shaft with keyway

With end-sided centering hole with “DS”

thread according to DIN 332, Part 2,

Edition 05.83

1) Keyway according to DIN 6885, Sheet 1, ed. 08.68. For details, refer to the

motor rating sheet!
