Product Description:
The LSM34N-10-602-E2-2KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. This motor is intended for closed-loop positioning and speed control in industrial automation, where it drives rotary axes or gear stages with precise electrical commutation. Its brushless design eliminates brushed contacts, reducing maintenance requirements in continuous-duty production lines while supporting responsive control of automated machinery.
The motor can deliver a continuous torque of 10 lb-in to hold or move a load steadily, while its peak capability rises to 39 lb-in during short acceleration bursts. Its electromagnetic efficiency is indicated by a torque constant of 0.37 Nm/A; each ampere from the drive therefore produces nearly four-tenths of a newton-meter at the shaft. Back electromotive force is characterized by a voltage constant of 45 V/krpm, which the drive must overcome to maintain higher speeds on the 230 V winding. The phase inductance reaches 23.8 mH, shaping current rise times and influencing the tuning bandwidth of the servo amplifier. Additional electrical parameters include a winding resistance of 4.0 Ω, which affects steady-state copper losses during operation. Mechanical power exits through a keyed shaft, allowing pulleys or couplings to transmit torque without slipping under changing loads.
An external holding brake engages at 24 VDC, keeping vertical or load-bearing axes stationary when motor power is removed. Position feedback is supplied by an incremental encoder with a resolution of 2,000 lines, enabling the controller to monitor shaft movement accurately. The encoder draws logic power from a +5 V supply through a 17-pin circular connector. The front bearing system can withstand a radial load of 54 lb at 6,000 rpm, supporting belt tension or overhung masses without premature wear. The overall package depth from the mounting face is 167 mm, allowing the motor to fit into spaces allocated for NEMA 34 frames while leaving clearance for cabling and airflow.
