Product Description:

The LSM100-46-454-S-2KA is a Kollmorgen industrial direct-drive motor suited for precision motion tasks. It features Kollmorgen's advanced control construction with optimized performance dynamics for precision automation requirements. This motor is engineered for use in applications where high positional accuracy and responsive speed are required for system efficiency. The motor’s direct-drive configuration eliminates the need for transmission components, reducing maintenance needs and enabling seamless integration into compact, high-performance systems.

This motor is engineered to operate at high velocity, supplying stable speeds to suit fast-cycle requirements. Its base velocity of 4500 rotations per minute allows it to provide swift responsive motion. Its high-speed capacity provides adaptable performance to suit a wide range of high-throughput operations. The motor is built to ensure accurate execution of motion profiles, sustaining consistent speed without overheating or degradation in performance. For enhanced response to control signals, the motor is constructed to offer very low resistance to speed changes. This enables it to respond quickly to changes in speed, ensuring smooth transitions in dynamic motion control processes. The motor can generate variable torque depending on load conditions. Under peak operation scenarios such as when the motor needs to stop or accelerate, the motor can provide enhanced torque of up to 16 Nm. This allows the motor to adapt its performance to changing load conditions in real time, maintaining stable operation even when there are changes in load.

The LSM100-46-454-S-2KA is designed to handle high power loads suited for intensive high-cycle tasks with a 21.2 A current tolerance. This level of current allows the motor to generate increased torque output when temporarily needed, such as during rapid acceleration, load disturbances or system startups. The motors optimized frame size and build weighs less than 7kg in total. This provides a manageable size for integration into various automation systems without compromising mechanical stability during operation.
