Product Description:
The MHD112B-024-PG0-LN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts commanded current into precise rotational motion and torque, making it suitable for indexing stations, gantry axes, and feed drives that demand accurate dynamic response. It operates as the electromechanical actuator in assemblies where digital controllers coordinate multiple axes. In servo applications, the motor works with the drive to correct position error in real time and maintain smooth axis motion under changing load conditions.
Its continuous torque at standstill reaches 28.0 Nm, allowing the shaft to hold process loads without external gearing. Heat is removed through liquid cooling, keeping the windings below insulation limits during extended duty. The housing carries a dust-tight, water-jet-resistant rating of IP65. Reliable operation is specified for 0 to 40 °C, and operation outside this range requires derating. Power enters through a connector positioned on the left side of the stator, which can simplify cable routing on mirrored machine frames. A digital servo encoder provides absolute feedback beyond 4,096 revolutions, and optical sensing supports fine interpolation. Winding code 024 indicates the resistance and inductance values used by the matched drive. The plain shaft mates directly with couplings, and a shaft seal helps prevent lubricant escape. Because the motor has no holding brake, static position must be maintained by the drive or external mechanics.
The mechanical interface uses a centering pilot of 130 mm and a flange side length of 192 mm, ensuring concentric mounting to gearboxes. Stator length B shortens the motor package for tight spaces and helps the unit fit compact machine layouts. Windings carry Class F insulation, which supports the thermal demands of the cooling circuit. System accuracy of ± 0.5 angular minutes permits fine positioning on assembly or machining axes. Installation altitude should not exceed 1,000 m above sea level, and storage temperatures between −20 and +80 °C help preserve encoder integrity.
