MKD041B-143-GP1-KN

The Bosch Rexroth Indramat MKD041B-143-GP1-KN servo motor from the MKD Synchronous Motors series delivers a robust solution for precision motion control applications. This straight connection type unit is engineered to provide rated power of 1.3 kW and sustain a maximum torque of 7.5 Nm with reliable performance. Weighing 5.5 kilograms, the MKD041B-143-GP1-KN achieves a high power-to-weight ratio essential for dynamic automation systems. Its integrated encoder system and resolver feedback guarantee accurate position detection during high-speed operations. The motor’s natural convection cooling and fully closed compact design ensure consistent functionality in demanding industrial environments.

The technical specifications of this servo motor underscore its engineering excellence. It features a winding code of 143 matched to a Motor Size 041 and Motor Length B for compatibility with compact drive assemblies. The device incorporates a Shaft Design with keyway and Shaft Seal to maintain mechanical integrity under load. The rotor’s inertia is precisely set at 0.45 x 10^-4 kg·m^2 to balance acceleration performance and torque response. Continuous torque at standstill is rated at 2.7 Nm, while the built-in Holding Brake Torque of 2.2 Nm secures the load when power is removed. The connector box houses standardized electrical connections, supporting both power and encoder circuits for seamless integration.

Operational features emphasize durability and usability. The servo motor supports a Rated Current of 8 A and can handle peak demands up to maximum current of 27 A without compromise. It tolerates an Ambient Temperature Range of -20°C to +40°C, ensuring reliable operation across varied climate conditions. The unit withstands radial forces up to Max Radial Load 140 N and axial forces up to Max Axial Load 57 N, enabling robust performance in multi-axis machinery. Resolver feedback (RSF) position detection provides relative position data with high immunity to electrical noise. Oil lubrication and a fully sealed housing contribute to low-maintenance operation and IP65-level protection against dust and splash water.

System integration is straightforward with Bosch Rexroth Indramat drive controllers, leveraging the motor’s Connection Type: Connection box and standardized encoder interface. The MKD041B-143-GP1-KN is ideal for applications such as CNC machining centers, robotic arms, packaging lines, and automated assembly systems. Its three pole pair design and compact form factor simplify installation in space-constrained environments. Maintenance protocols are minimized by the closed-loop design and robust sealing, making this servo motor an optimal choice for high-precision, high-reliability industrial automation solutions.
