Product Description:

The LSM75-29-602-E2-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It is intended for closed-loop industrial automation where precise speed and torque regulation are required, such as indexing tables or packaging axes. By combining electronic commutation with a permanent-magnet rotor, the motor converts drive current into controlled mechanical rotation that can be coordinated by a servo amplifier in multiaxis machinery. This arrangement allows accurate acceleration, steady running, and repeatable position control during automated cycles.

In continuous operation, the unit delivers 3.3 Nm of torque, which is the sustained twisting force available during normal duty. That output is proportional to the torque constant of 0.40 Nm/A, so each additional ampere from the drive increases shaft torque by four-tenths of a newton-meter. The rated winding voltage is 230 VAC, which matches amplifier outputs designed for this motor class. Speed capability reaches 6000 rpm, allowing high rotational speed in compact servo axes. For short acceleration demands, the motor can accept up to 33 A(pk), and its eight-pole design supports responsive velocity control. A phase resistance of 1.32 Ω contributes to copper losses that must be removed by the motor’s cooling path.

The back electromotive force constant is 49 V/kRPM, which gives predictable voltage generation as speed rises. For brief overload periods, the motor can produce 13.2 Nm of peak torque. Fast reversals are supported by the low rotor inertia of 0.000044 kg·m², which reduces stored rotational energy and helps the axis change speed quickly. The winding inductance of 12.4 mH helps smooth current ripple, and the 2000-line incremental encoder supplies position feedback to the control loop. The motor has a net mass of 3.9 kg, which suits compact machine assemblies and helps limit added load on moving equipment.
