Product Description:
The MHD115C-058-PG1-BN is a servo motor built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It supplies closed-loop rotary motion for machine axes in automated transfer lines, gantries, and machining centers. This makes it suitable for coordinated servo axes that must hold position accurately during rapid starts, stops, and direction changes. The motor has frame size 115 and C frame length, supporting high torque density while keeping the overall envelope compact for installation on machine frames. An output connector for the power leads simplifies cable routing and helps keep wiring organized in enclosed equipment or moving energy chains.
At stall, the motor can deliver 70.0 Nm of continuous torque, allowing static positioning or low-speed feed duties without thermal overload. Heat from the stator windings is removed by integrated liquid cooling, so rated output remains available even when the housing is enclosed by machine panels. The enclosure is rated IP65, which helps block dust and withstand routine washdown spray. Position feedback is obtained through an optical digital encoder with a system accuracy of ± 0.5 angular minutes, which supports precise contouring and repeatable axis motion. Mounting uses an ISO flange with a diameter of 192 mm, and an internal holding brake secures the shaft when power is removed. The 058 winding code indicates the electrical winding used for this motor variant.
A storage temperature range of -20 to +80 °C helps protect the motor during shipment and warehousing. Continuous operation is intended for ambient temperatures from 0 to 40 °C, keeping the insulation system within its normal thermal range during duty. Precise alignment is supported by a 180 mm centering pilot, and the plain shaft is fitted with a shaft seal. The motor uses multi-turn absolute feedback of more than 4096 revolutions, which allows the axis position to remain available after power interruptions without a homing cycle. Power and feedback wiring exit on side B, and the motor can be installed at altitudes up to 1000 m above mean sea level without derating.
