LSM165-221-454-M-2KA by Kollmorgen

The Kollmorgen LSM165-221-454-M-2KA servo motor from the LSM Brushless Servo Motors series is engineered for precision automation and high-reliability performance. This brushless 8-pole design delivers 25 Nm continuous torque and up to 100 Nm maximum torque while maintaining exceptional energy efficiency and durability. A built-in multi-turn high-resolution encoder provides precise position feedback and eliminates the need for homing procedures after power interruptions. Its compact form factor and advanced thermal management facilitate integration into demanding industrial systems without sacrificing torque density or dynamic response.

The LSM165-221-454-M-2KA features a 24 VDC input voltage rating and operates reliably across an ambient range of 0 to 45°C with a protection class of IP55 to guard against dust and water ingress. It tolerates a relative humidity up to 95% (non-condensing) and can be stored safely between –30 to 70°C. The motor’s inductance of 3.6 mH ensures stable current control, and its stall current of 30.3 A defines peak drive requirements. With a nominal speed of 4500 RPM and a high KE constant delivering 109 V per 1000 RPM, the motor achieves rapid acceleration without excessive heat buildup. A standard 12-month warranty underpins the component’s industrial robustness and reliability.

Operational performance is enhanced by low rotor inertia, which enables rapid acceleration and deceleration cycles with minimal energy loss. The brushless construction minimizes maintenance intervals and extends service life, while the multi-turn encoder retains absolute position data through power cycles, improving system uptime. The motor’s high torque-to-inertia ratio allows precise control of dynamic loads, making it ideal for robotic indexing, conveyor tensioning, and pick-and-place mechanisms. Built-in thermal stability features maintain temperature rise within safe limits, reducing the risk of thermal derating under continuous high-load conditions.

System integration is seamless with standard servo drives supporting the LSM Brushless Servo Motors series, simplifying network communication and tuning workflows. The comprehensive specification set, including Input Voltage, Maximum torque, Protection class, and Operating temperature, enables accurate system modeling and performance prediction. This motor excels in industrial automation, robotics, packaging machinery, and material handling applications where precision, repeatability, and durability are paramount.
