Main features and advantages:
The REXROTH MKD071B-035-KG1-KN stands out for its remarkable torque output and dynamic performance. With a rated torque of 3.5 Nm, it can effortlessly handle medium to heavy loads, making it a top choice for applications such as conveyor systems in logistics centers that need to move large volumes of goods continuously. Its advanced motor design allows for rapid acceleration and deceleration, which is essential in applications like pick – and – place robots in electronics manufacturing, where quick and accurate positioning is required to meet high production rates.
Constructed with a durable cast aluminum housing, the motor offers robustness without adding excessive mass, weighing approximately 7.8 kg. It operates dependably within a temperature range of 0°C to 40°C (with derating up to 60°C) and features an IP65 protection rating. This makes it suitable for use in environments where there is a presence of light dust or moisture, such as in food and beverage production facilities where equipment may be subject to periodic cleaning. The integrated multi – turn encoder provides highly detailed position feedback. This ensures that even during extended operation and repeated movements, the motor maintains consistent accuracy, which is vital for applications that require batch – to – batch consistency, like in the production of precision components.
Compatibility is one of the key strengths of the REXROTH MKD071B-035-KG1-KN. It integrates smoothly with Rexroth’s IndraDrive Cs and IndraDrive Mi controllers. It also supports communication protocols like PROFINET and CANopen, which are fundamental for seamless integration into modern Industry 4.0 systems. This flexibility enables it to work in tandem with other components within the MKD series, as well as larger motors from different Rexroth product lines, such as the MHD115C – 058 – PG1 – BA. This creates scalable motion control solutions that can be tailored to evolving production requirements.

Installation and maintenance:
Before installing the REXROTH MKD071B-035-KG1-KN, it is crucial to verify that the mounting surface can support its 7.8 kg weight without any vibration. Uneven mounting can lead to premature bearing failure and reduced motor lifespan. Use a precision laser alignment tool to ensure concentricity within 0.1 mm when aligning the motor with the driven load. This reduces shaft stress during operation and improves the overall efficiency of power transmission. The motor’s IP65 protection rating allows for use in environments with light dust or moisture, but it is essential to ensure that cable entries are properly sealed using compatible glands. This helps maintain the protection rating and prevents the ingress of contaminants that could damage the motor. In systems with multiple motors, carefully route encoder cables separately from power cables. This minimizes electromagnetic interference, which can otherwise affect the accuracy of the encoder’s position feedback and, in turn, the motor’s positioning accuracy.
Maintenance of the REXROTH MKD071B-035-KG1-KN is focused on preserving its high – performance capabilities over the long term. Conduct monthly visual inspections to check for any loose connections or signs of overheating, such as discolored wiring. Although the motor’s bearings are lifetime – lubricated, any unusual noise during operation should be investigated promptly. This could be an indication of misalignment or excessive load, both of which can cause damage if left unaddressed. Use the drive’s diagnostic tools to verify the encoder’s functionality quarterly. This ensures that the position feedback remains accurate, which is critical for applications that rely on precise positioning. When cleaning the motor’s exterior, use a dry cloth. Avoid using high – pressure water jets or harsh chemical cleaners, as these can damage the housing’s protective coating and compromise the IP65 protection rating over time.
