Features of Indramat MKE Servomotors

Indramat MKE servomotors are engineered for reliability, safety, and efficiency in demanding environments. Designed for use with Indramat drive controllers, these motors are part of a highly functional and integrated drive system capable of delivering precise motion control across a broad range of applications.

With a brushless design, low-maintenance profile, and high-performance permanent magnets, MKE servomotors provide outstanding dynamic response and endurance, making them ideal for applications in hazardous, explosive, or wet environments.

Ambient Operating Conditions

To ensure proper functioning and longevity, MKE servomotors must be operated within the following parameters:

• Temperature Range: 0 °C to 40 °C

• Installation Altitude: 0 to 1000 meters above sea level

Operating beyond these limits can impact the nominal performance and potentially shorten the motor’s lifespan.

Key Features of Indramat MKE Motors

MKE servomotors stand out due to several advanced features that enhance performance and usability:

• High Operational Reliability: Built for continuous operation in harsh industrial environments

• Overload Protection: Integrated temperature sensors monitor internal conditions and prevent overheating

• Continuous Start-Stop Operation: Enabled by electronic commutation

• Fast and Simple Startup: Plug-and-play integration with Rexroth drive systems

• High Dynamics & Overload Capability: Optimized torque-to-inertia ratio with superior heat dissipation between windings and housing

These motors are perfectly suited for automated assembly, printing presses, material handling, and food processing equipment, particularly in ATEX-rated or washdown applications.

Electrical Connection Guidelines

To ensure optimal performance and electromagnetic compatibility (EMC), Indramat recommends using only Bosch Rexroth-certified cables for all electrical connections. These cables are:

• UL/CSA approved

• Designed to withstand extreme mechanical loads

• Engineered for superior EMC shielding

• Compatible with Rexroth’s integrated motor and drive architecture

Maintenance Tip:
Electrical and mechanical connections should be inspected according to the machine’s maintenance schedule or, at minimum, every 1,000 operating hours.

FAQs

 What housing designs are available?

MKE motors come in two housing designs:

• Design E: Compliant with European ATEX standards

• Design U: Compliant with American NEC standards

The motor's type code will indicate which housing standard it adheres to.

 Are MKE motors suitable for explosive areas?

Yes. MKE motors are certified for use in potentially explosive atmospheres. They meet ATEX standards and feature:

• Flameproof housings

• IP65 ingress protection

• Resistance to corrosion in spray-down and washdown environments

 How long does it take for an MKE motor to cool down?

After being powered down, MKE motors typically take around 140 minutes to cool completely. This is approximately five times the thermal time constant of the motor.
