Indramat MKE

Indramat MKE Motors

Indramat MKE digital AC motors, when paired with digital intelligent INDRAMAT drive controllers, form a cost-efficient and versatile drive system suited for areas with explosive atmospheres. These motors are built with pressure-resistant housing compliant with EN 50014 standards, ensuring extreme reliability even under challenging conditions. The brushless design and lifetime-lubricated bearings contribute to a maintenance-free operation, while the sealed motor design with an IP65 protection category allows for safe use in adverse environmental settings. Temperature monitoring offers overload protection, ensuring longevity and consistent performance. The motors are also noted for their high power output, dynamic performance due to a favorable power-to-weight ratio, and impressive overload capacities, enhanced by efficient heat conduction from the stator windings to the motor's exterior wall.

Technical Data

The technical data and speed-torque curves provided for MKE motors take into account various conditions to ensure accuracy. These conditions include a maximum environmental temperature of 40°C and the motors having an insulated structure with an aluminum flange. If the motors come with the option of a holding brake, the provided data corresponds to motors that are equipped with this brake. Additionally, the motors are considered to have a radial shaft sealing ring. These stipulations are put in place to standardize the data and performance metrics, ensuring that the information reflects a consistent set of environmental and structural variables.

Appropriate Use

Rexroth MKE series motors are designed for use as rotary main and servo drive motors across various industries. Typical applications include machine tools, printing and paper-processing machines, packaging and food-processing machines, and metal-forming machines. They come in different types offering varied driving powers and interfaces to suit specific applications. Moreover, controlling and monitoring these motors may necessitate the addition of extra sensors and actuators.

For optimal performance, these motors are certified for use in environments where ambient temperatures range from 0° to +40°C and at installation altitudes from 0 to 1,000 meters above sea level. It's important to note that operating the motors outside these conditions could void the certification. In cases where the motors need to be used outside the recommended temperature range or altitude, it's advised to contact the sales office for guidance on obtaining special certifications.
