1 Introduction
This chapter describes how to use the present documentation (refer to
the chapter entitled “About this Documentation”) and includes a general
representation of the product in Chapter 1.1.
1.1 Product Presentation
In connection with the digital intelligent drive controllers by Rexroth, the
digital MKD AC motors offer cost-effective automation systems with an
extensive functionality for the following fields of application:
• Machine tools
• Printing and paper industries
• Handling and automation
• Packaging machines and food
• Food industry (selected motor types style “non-painted”).
MKD motors are characterized by the following advantages:
• High operational reliability
• Maintenance-free operation (owing to the brushless design and use
of bearings grease-lubricated for their entire service life)
• Use under adverse environmental conditions is possible (owing to the
completely closed motor design in IP 65 degree of protection
• Overload protection (owing to motor temperature monitoring)
• High performance data
• High dynamics (owing to the favorable ratio of torque to inertia mass)
• High overload capability (owing to the favorable heat dissipation from
the stator windings to the outside wall of the motor housing)
• Peak torque utilizable across a wide speed range (owing to electronic
commutation)
• Continuous start-stop operation possible with high repeat frequencies
(owing to electrical commutation)
• Easy attachment to the machine (owing to flange according to DIN
42948)
• Any installation position desired
• Direct overhung mounting of pinions and belt pulleys (owing to the
bearing being designed for high radial loads)
• Easy cabling (owing to cable sets, available in various designs)
• Simple and quick startup (owing to data memory in the motor encoder
unit)
