Product Description:

The LSM165-173-304-M-0KA is a Kollmorgen brushless motor design built in accordance with international quality and operation standards. This motor unit is perfect for customers working in rugged industrial environments; it is designed to withstand external interference and does not require maintenance operation throughout its service life. The LSM165-173-304-M-0KA motor unit features an output shaft that is able to reach an operation speed of about 3000 revolutions per minute; this shaft comes with a keyway that provides smooth torque transmission without any risk of relative movement. The power output of this industrial motor unit during its operation is estimated to be about 4 kilowatts.

The LSM165-173-304-M-0KA motor unit operates with an input current of 11.7 amperes, and a 360 alternating current voltage supplied at a frequency of about 200 hertz. Under standard operating conditions, the torque output of this unit is approximately 19.5-newton meters, and its internal phase resistance is also about 0.9 ohms. There are two connectors integrated into this unit; the power connector is present on top of the unit, while the motor feedback connection is integrated at the back. Both the power and motor feedback connectors preserve the motor's high protection class. The LSM165-173-304-M-0KA supports the use of direct mount pinions and belt pulleys for cost-effective applications; it also features a machine design that has been simplified with standard gearboxes and mounting plates.

The LSM165-173-304-M-0KA industrial motor unit contains ball bearings with an estimated service life of 20,000 hours under normal operation conditions. The radial load that can be supported by the output shaft of this motor during operation is about 63 kilograms. To prevent electrical noise during the operation of this unit, wire length should be kept as short as possible, and shielded motor cables should be used when necessary to prevent electromagnetic interference.
