Product Description:

The LSM165-173-304-S-2KA Brushless servo motor from Kollmorgen is ideal for applications requiring great torque precision. The brushless servo motor is able to fulfill the requirements of automated systems for dynamic motion control due to its small mechanical profile and powerful torque output.

The LSM165-173-304-S-2KA brushless servo motor comes with a peak torque capacity of 54.6 Nm at a rated speed of 3000 rpm, in addition to 19.5 Nm of continuous stall torque and 12.7 Nm of continuous rated torque. The brushless servo motor operates dependably under a wide range of loads, and its rotor inertia of 0.00128 kg·m² ensures that acceleration costs are kept to a minimum. The servo motor’s top corner speed is determined to be 2400 revolutions per minute. In addition to ensuring the structural integrity of the system, the power wire gauge of 14 AWG and the shaft diameter of 32 mm both contribute to the efficient transfer of power. In order to guarantee compatibility with the standard mounting configurations, it is essential to have a flange measuring 142 millimeters by 130 millimeters and a pilot diameter measuring 100 millimeters.

Featuring a 16.5 A continuous stall current rating, the LSM165-173-304-S-2KA servo motor is designed for use in industrial automation and ensures repeatable performance. A significant factor that contributes to the servo motor's greater stiffness is the 3.5 millimeter thickness of its flange. Additionally, the motor's shaft length is 88 millimeters, and its bolt circle diameter is 165 millimeters. The brushless servo motor is suitable for use in activities that demand precise control of torque and a high degree of precision in rotation because of these features, which make it acceptable for use in such tasks.
