Product Description:

The MS2N07-D0BRA-BMVH2-RNNNN-NN is a lightweight servo motor designed for industrial motion regulation. It demonstrates skilled mechanical engineering with precision flange construction that is engineered for exceptional accuracy and reliability. The flange size of 140 mm, with improved accuracy, offers superior mounting precision that eliminates runout tolerances common in standard flange designs. This precision is crucial for high-accuracy applications like machine tool spindles and coordinate measuring equipment, where even tiny deviations can affect performance. The enhanced flange precision ensures perfect alignment between the motor and the equipment without needing mechanical adjustments.

The MS2N07-D0BRA-BMVH2-RNNNN-NN motor has a smart cooling design that uses forced cooling technology to prevent heat build up during constant high-power use and tough duty cycles. This system actively circulates air around key motor parts, allowing for sustained operation at maximum torque levels. The motor's significant maximum torque of 79.7 Nm, combined with good thermal management, lets it manage tough acceleration profiles and heavy cutting tasks. The mechanical design of this motor includes a carefully made smooth shaft with a seal, featuring a 32 mm diameter and extending 58 mm in length for better coupling flexibility and strength. The shaft seal protects against contamination. The smooth surface reduces stress points that could weaken fatigue resistance during high-speed operations up to a maximum of 6000 rpm. The 130 mm spigot size with M10 mounting holes provides a secure mechanical connection,

The motor comes with IP65 protection rating that guarantees complete dust protection and water resistance. Key electrical features of the motor include precisely controlled winding resistance of 0.327 Ohm at 20°C and a winding inductance of at least 5.06 mH, which gives optimal electrical time constants for responsive control system performance.
