Indramat MKD

Indramat MKD Motors

MKD motors by Rexroth are AC servo motors tailored for both servo and main drive applications. They are specifically designed to be integrated with Rexroth's digital intelligent drive controllers, enhancing cost-effectiveness and functionality within automated systems. The application fields for MKD motors are diverse, including machine tools, printing and paper industries, handling and automation, packaging machines, food processing, and they are particularly noted for a non-painted motor type suitable for the food industry.

The benefits of using MKD motors are numerous, providing high operational reliability and a maintenance-free operation thanks to their brushless design and lifetime-greased bearings. These motors are suitable for use under adverse environmental conditions, featuring an IP 65 degree of protection with a completely closed motor design. They also include features such as overload protection through motor temperature monitoring, high performance data, dynamic operation due to a favorable torque to inertia mass ratio, and high overload capability, supported by efficient heat dissipation from the stator windings to the motor housing's outer wall. These characteristics make MKD motors a reliable choice for various industrial uses that require durability, efficiency, and precision.

MKD Specifications & Type Codes

The MKD Motors come in various sizes: 025, 041, 071, 090, 112, each containing several differences in specifications. Please make sure your selected MKD motor is in line with your automation needs. Always refer to the official Indramat documentation.
