Rexroth Kit Motors

General Information

Kit motors consist of individual components that are mounted to a moving

and as static part of the machine’s mechanical system and functionally

put together to form a motor.

A kit motor consists of the following components:

• electrically active part with thermo sensor

• electrically passive part

• measuring system

• bearing

The electrical parts of the kit motor are supplied by Rexroth, the

measuring system and the bearing are provided on the machine side.

Rexroth kit motors are manufactured according to the "asynchronous

motor" or "synchronous motor" functional principles. With regard to

control the functional principles have different requirements:

• In the case of synchronous motors, the current in the windings of the

stator must have a fixed allocation to the permanent magnetic field of

the rotor so that the maximum torque or the maximum force is

generated.

• In the case of asynchronous motors there is no fixed allocation

between stator and rotor required in order to generate the maximum

torque or the maximum force.

Rexroth Kit Motors, Synchronous

Brief Description

The following Rexroth kit motors are manufactured according to the

"synchronous motor" functional principle:

• LSF linear motors

• MBS and MBT rotary motors

As the motor is assembled in the machine, stator, rotor and measuring

system can only be put together on site. The electric-magnetic-

mechanical allocation of the synchronous motor is therefore only to be

made on site. This is done by determining and setting the commutation

offset.

Note: The measuring system should be realized with high resolution

and as a motor encoder that can be evaluated in absolute

form (see also "Absolute Measuring Systems"). If it is

necessary to use an incremental measuring system the use of

encoders with square-wave signals should be avoided!

The commutation offset can be determined with different methods. The

method is chosen in accordance with the axis geometry, the practicability

and the success of the respective method depending on the mechanical

axis system:

• measuring method for relative motor encoder and Hall sensor box

(distance measurement, currentless Å only possible with Rexroth

linear kit motors, see documentation "Hall Sensor Box SHL01.1")
