Product Description:
The LSM75-10-602-E2-0KA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. As a compact rotary actuator, it integrates with digital drives to provide precise closed-loop positioning and velocity control in packaging equipment, pick-and-place heads, and other light automation axes where limited space and fast cycles are critical. Its 118 mm depth from the mounting face reduces the installation space required behind the driven mechanism. The motor weighs 2.3 kg, which reduces the additional mass placed on dynamic gantry axes and other moving assemblies.
The motor delivers a continuous torque of 1.1 Nm, allowing it to sustain rated loads without excessive temperature rise. For short acceleration bursts, its output increases to 4.4 Nm, providing additional torque for rapid changes in speed. When energized from a 230 VAC bus, the electromagnetic design supports synchronous speeds up to 6000 rpm, enabling direct coupling to high-speed mechanisms. A torque constant of 0.37 Nm/A relates the commanded current to the developed torque and supports accurate current-loop control. The 2.5 mm key depth accommodates compatible couplings without requiring an intermediate shaft adapter. At maximum speed, the frame supports a radial load of 24 kg when the connected mechanism applies force within the permitted loading direction.
The motor has a back EMF constant of 45 V/krpm, so the generated voltage rises in proportion to rotational speed. Coil energy storage is governed by a winding inductance of 23.8 mH, which affects how quickly current changes after the drive applies voltage. Copper loss is influenced by a winding resistance of 4.0 Ω, and the drive must account for the resulting heat during rapid duty cycles. A rotor inertia of 0.000022 kg·m² supports quick acceleration while helping limit overshoot in lightly damped loads. A 2,000-line incremental encoder supplies quadrature feedback for high-resolution position and velocity control. The keyway shaft provides positive torque transfer to pulleys, couplings, or gearheads and helps prevent rotational slippage under changing loads.
