Product Description:

The Servo Motor LSM100-22-454-E2-2KA comes from Kollmorgen as its manufactured product for industrial automation. This motor comes with a 100 mm frame dimension and extends to 433 mm with a brake installed. The base motor measures 320 mm in length while the flange consists 190 mm in width. The motor shaft consists of tough ST-60 steel material.

The weight of the LSM100-22-454-E2-2KA servomotor by itself reaches 38.5 kg while it grows to 41.7 kg when the brake is installed. When equipped with a brake unit the rotor inertia rate becomes 0.00686 kg·m² but the value rises to 0.00856 kg·m². The designed product includes eight poles that allow the motor to rotate effortlessly while delivering optimal electromagnetic results. This motor functions at an electrical specification of 460V rated voltage. At 4500 RPM this motor operates with continuous torque output of 25 Nm. The LSM100-22-454-E2-2KA servomotor delivers a peak torque output of 105 Nm which makes it compatible with demanding high-load operations. The peak load stall current amounts to 30.4 Amps and the maximum peak current reaches 107.5 Amps during operation. This device offers a torque constant of 1.84 Nm/Amp rating together with a voltage constant of 222 V/kRPM.

The winding resistance of the LSM100-22-454-E2-2KA servomotor measures 0.38 Ohms at 25°C and its winding inductance equals 6.94 mH. A 17-pin feedback connector connects to the motor which uses the E2 incremental encoder. A safety brake uses 24VDC power under option 2 and is built within the motor structure. The motor receives its power supply through a size 3 connector which enables up to 97 A RMS current. The product release includes both a keyway feature along modification options that have the mark KA.
