Product Description:

Belonging to the MSM series, the Kollmorgen MSM165-93-204-E2-0KA is a high-torque servo motor for demanding jobs in industry.

This servo motor's basis is built on applications that require stability and high torque, thanks to its robust mechanical components and great accuracy. The 6-pole configuration of the servo motor enables it to maintain a consistent torque performance of 10.5 Nm while reaching a maximum torque of 34 Nm. This makes it suitable for use in robotics, machine tools, and packaging. At 2000 RPM, this motor operates in a balanced manner for both torque-based and speed-based tasks. Through its electrical characteristics, the motor achieves both its high-performance mark and accurate control perfection. The motor accurately controls torque using current due to its torque constant (Kt) measurement at 1.86 Nm/Amp and its back EMF constant (Ke) value at 225 V/kRPM. Together, the motor's 5.7 Ohms phase-to-phase winding resistance and reported 60 mH winding inductance keep it running efficiently and reduce electrical noise.

Before the brake is installed, the MSM165-93-204-E2-0KA's rotor moment of inertia is 0.0022 kg-m², and when the brake is in place, it is 0.003 kg-m². The reduced rotor inertia facilitates smooth acceleration and deceleration and allows for excellent control stability. This motor can operate efficiently under challenging starter conditions thanks to its peak stall current of 6.2 A and peak maximum current of 24 A. The motor weighs 13.9 kg with brake installation, yet its weight is 12 kg without the brake, making it durable enough for heavy-duty tasks. Given its strength and capacity to withstand heavy mechanical stresses, ST-60 steel is used to make the shaft. It can be purchased at Wake Industrial with a one-year warranty.
