Safety Instructions
The following instructions apply to all procedures associated with the motor. Read
these instructions carefully and follow them closely.
• Use necessary personal protective equipment when working with the motor.
• Support the motor properly. Make sure the motor cannot fall over or turn around
by accident.
• Use only appropriate equipment and attachments for lifting and transferring the
motor.
• Do not use magnetic lifting devices.
• Always use the lifting equipment properly and check the load-bearing capacity.
• Prevent unintended use of the motor during installation and maintenance
procedures by preventing pressurization of the hydraulic lines.
• The operating temperature of the motor may be over 60 ºC (140 °F), which is hot
enough to cause severe burns. Beware of hot hydraulic uid when disconnecting
the hydraulic connections.

Motor Description
Working principle
B200 series motors are rotary-housing. This means the motor shaft and the cylinder
block remain in place while the motor is running.
Figure 2. The main components of the motor.
1. Shaft
2. Distribution valve
3. Cylinder block
4. Piston
5. Cam roll
6. Cam ring
7. Bearings
8. Housing
9. Hub
10. Shaft sealing
The rotation of the motor is achieved by feeding pressurized hydraulic uid through
the motor shaft to the distribution valve. The distribution valve directs the ow to the
pistons which are on a power stroke. Pressure pushes the pistons and cam rolls
outwards against the cam ring on the housing. The waveform of the cam ring
transforms the force into torque. When the pistons reach the end of the power stroke,
the distribution valve closes the ow to the pistons and switches the pistons to a
return stroke.The cam ring pushes the pistons back into the cylinder block preparing
them for the next outward power stroke.
Figure 3. Flow to the pistons.

tons.

More detailed information and mounting dimensions for each brake device can be found
on the product datasheet.
The drum brake increases the length of the motor assembly and aects the oset value of
the vehicle wheel rim.
Adding lubricant into the seal protector is prevented.
