Product Description:
The MKD112A-058-GG0-BN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It forms the rotary actuation element in industrial automation lines, turning drive-supplied current into controlled mechanical output so that gantries, packaging stations, or material-handling axes can index or follow motion profiles with consistent accuracy. A 112-frame housing and an A length code place the unit in the mid-power class while keeping envelope dimensions suitable for cabinets with limited depth.
This model supplies a continuous standstill torque of 15.0 Nm, giving servo drives enough holding force to resist static loads without overheating. The motor aligns with adjacent mechanics by means of its 130 mm centering diameter, a pilot surface that keeps the shaft concentric with the driven element. Mounting holes are arranged on a 192 mm square flange, a standardized pattern that matches gearboxes and brackets in the same size range. Power and feedback cabling exit on side B, so routing can remain clear of moving parts on the opposite face. The unit uses an output connector instead of captive leads, allowing rapid connection and shield continuity through circular plug-in hardware.
Position feedback is generated by a resolver, which provides analog sinusoidal signals that the drive uses for relative commutation and speed control. Because the motor is supplied without a holding brake, external locking or drive-generated torque must secure vertical axes during power loss. A plain shaft transmits torque directly and suits couplings that clamp on a smooth journal, while a shaft seal helps protect the interior bearings from coolant splash or dust. The 058 winding code identifies the stator turns and resistance used for this motor, matching its electrical characteristics to compatible MKD drives for resolver-based relative position operation.
Frequently Asked Questions about MKD112A-058-GG0-BN:
Q: What is the continuous torque at standstill for the MKD112A-058-GG0-BN motor?
A: This servo motor has a continuous torque of 15.0 Nm at standstill, suitable for maintaining precise position under load.
Q: What type of encoder does the MKD112A-058-GG0-BN use for position feedback?
A: The MKD112A-058-GG0-BN features resolver feedback (RSF) for position detection, providing relative position information for motion control systems.
Q: What is the shaft design of the MKD112A-058-GG0-BN servo motor?
A: The shaft on the MKD112A-058-GG0-BN is a plain shaft, optimized for direct coupling without a keyway.
Q: Does the MKD112A-058-GG0-BN motor include a holding brake?
A: This model does not include a holding brake, so external braking will be required for applications needing shaft holding at power loss.
Q: Where is the electrical connection located on the MKD112A-058-GG0-BN?
A: The electrical connection for this motor is located at Side B using an output connector, ensuring convenient cabling alignment in installations.
