Product Description:
The MHP115B-058-HP1-ANNNNN is a synchronous motor produced by Bosch Rexroth Indramat within the MHP Synchronous Motors series. It uses a permanent-magnet rotor and closed-loop feedback to deliver accurate rotary motion for packaging lines, gantry axes, and similar industrial automation tasks. Its 115 mm frame size and B length place it in the mid-torque range of the series, making it suitable for axes that need precise motion with a compact installation envelope. Insulation class F permits winding temperatures up to 155 °C during continuous duty, which supports stable operation under sustained electrical loading.
The motor develops a continuous standstill torque of 50.0 Nm when cooled by natural convection, allowing it to support static loads without auxiliary airflow. For power-off holding or use on vertical axes, an integrated brake supplies up to 70.0 Nm of static holding torque. Position and speed are returned to the drive by an incremental encoder with 2048 increments, which provides fine feedback resolution for servo control. The enclosure carries an IP65 rating that blocks dust ingress and resists low-pressure water jets on the machine exterior. These features allow the motor to operate on exposed machine frames where accurate feedback and dependable holding capability are both required.
Operation is intended for ambient temperatures from 0 to +40 °C, so the surrounding air must stay within that range for normal thermal performance. Mechanical output is transferred through a keyed shaft with a sealing ring, and the seal helps protect the shaft exit from contamination and moisture during routine machine use. Power cabling connects through a connector on side A, which can simplify routing when the flange faces the load and cable space is limited. The motor uses winding code 058, indicating the electrical configuration matched to compatible Rexroth drives. This arrangement keeps the electrical and mechanical interfaces straightforward for machine layouts that need controlled motion and secure shaft coupling.
