Product Description:
The MHP041B-144-HP0-UNNNNN is a permanent-magnet synchronous motor in the MHP Synchronous Motors series. Intended for integration into compact servo axes, it converts drive current into controlled torque for tasks such as indexing, feed drives, and pick-and-place mechanisms. The motor functions as the rotating element inside an Indramat drive train, where closed-loop control supports positional accuracy and repeatability across varied industrial automation platforms. Because it is a permanent-magnet synchronous design, it is well suited to servo applications that require predictable torque response and accurate motion control across repeated cycles.
The electromagnetic output is characterized by a continuous standstill torque of 2.7 Nm when only ambient airflow is available. An F-class insulation system permits winding temperatures up to 155 °C, allowing the stator to handle the thermal load produced by cyclic acceleration. Position feedback is provided by an incremental encoder with 2048 increments, giving the controller high-resolution phase information for velocity regulation and commutation. Power is fed through a connector that can be turned 270°, allowing the cable to exit in several directions without stressing the terminals. The housing is sealed to IP65, which helps protect internal components from dust and water jets during routine washdown. These features help the motor maintain stable electrical and mechanical performance during repeated start-and-stop motion.
The motor can operate between 0 °C and +40 °C ambient, which suits most indoor machine enclosures. A keyed shaft with a sealing ring provides positive torque transmission while helping prevent lubricant migration into connected gear elements. It is built in size 41 with length code B and uses winding code 144, pairing the mechanical envelope with the assigned electromagnetic setup. The unit is delivered without a holding brake, so static load retention must be provided by the drive controller or by external mechanical restraint when the axis is stopped.
