Product Description:
The MKD112B-058-GG0-BN servo motor is produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It uses a permanent-magnet synchronous design for operation with digital drive controllers, which lets the drive regulate speed and position with high accuracy during changing loads. In automated machinery, the motor converts electrical input into controlled shaft rotation for conveyors, gantries, and tooling spindles. Because it is intended for closed-loop motion control, the motor responds quickly to command changes and supports smooth velocity regulation during indexing, transfer, and synchronized machine movements. The unit belongs to the 112 frame size and B length class, placing it in a mid-power range suited to point-to-point positioning and interpolated motion.
At standstill, the motor delivers a continuous torque of 28.0 Nm, so it can maintain load-producing force at zero speed within permitted operating conditions. The centering shoulder measures 130 mm, which helps align the housing concentrically on the machine plate during mounting. Rotor position is reported through resolver feedback (RSF), a two-phase analog sensing system that remains reliable under vibration and changing temperature. A square 192 mm mounting flange follows the IEC pattern for secure attachment to the machine. Winding code 058 sets the electrical characteristics expected by compatible drive modules and supports correct matching with the drive.
All power and feedback conductors exit on Side B, which helps keep cable routing away from moving machine elements and crowded coupling areas. A single output connector carries the motor phases and signal lines through one connection point, reducing the number of external entry points on the housing. Mechanical power is transmitted through a plain shaft without keyways, which supports backlash-free clamping hubs in precision couplings. A fitted shaft seal helps keep coolant mist and lubricants away from the internal bearing area. The motor is supplied without a holding brake, so any static holding force must come from the drive or an external mechanical device.
