Product Description:

The MHP115A-058-HG1-RNNNNN belongs to the MHP Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an AC servo unit intended for closed-loop positioning and velocity control in automated machine axes, conveying modules, and handling gantries where precise rotary motion supports coordinated multi-axis sequences. When used with a compatible drive controller, it converts electrical commands into controlled shaft motion for synchronized travel, repeatable positioning, and stable speed regulation during continuous machine operation.

Rated for a continuous torque of 32.0 Nm under natural convection, the motor delivers constant stall output without forced cooling. A permanent-magnet holding brake provides a peak retentive torque of 70.0 Nm, allowing vertical loads to remain fixed during power loss. The drive end uses a plain shaft with a sealing ring, so oil tightness is maintained while accommodating couplings or pulleys. Position feedback is generated by an incremental encoder with 2048 increments, giving the drive controller high-resolution signals for tight speed loops. Component ingress protection reaches IP65, helping protect internal parts from dust and low-pressure water jets during machine operation. Thermal exchange relies on a ribbed housing designed for natural convection, and the stator uses winding code 058 so its electrical values match the designated drive amplifier.

The 115 frame format suits medium-torque machinery such as indexing tables and tooling spindles. Windings use Class F insulation, permitting internal conductor temperatures up to 155 °C while maintaining dielectric integrity. Ambient operation is specified from 0 to +40 °C, which suits typical factory conditions without supplemental climate control. Length code A keeps the motor compact, and the right-side power connector helps route cables along linear machine elements and adjacent moving assemblies.
