What is the rated torque of MHD112D-027-NP0-RN motor?

The rated torque ranges from 27.3 to 59.2 Nm depending on cooling and speed configuration. The variation allows flexible adaptation to different mechanical load requirements.

How does the motor’s peak current affect operation?

The peak current of 142.2 A determines the motor’s maximum short-term torque capacity. The high current tolerance ensures transient load stability during demanding acceleration phases.

What is the significance of the torque constant value?

The torque constant of 1.7 Nm/A defines torque output per ampere of current. The parameter enables precise torque control essential for servo drive tuning and system efficiency.

How does cooling type influence rated performance?

The natural and surface cooling options directly affect continuous torque and current capacity. The enhanced thermal dissipation of surface cooling supports higher continuous load operation without overheating.

What does the IP65 protection rating imply?

The IP65 rating ensures complete dust protection and resistance to low-pressure water jets. The enclosure protection supports reliable performance in industrial environments with moderate exposure to moisture and particulates.
