Product Description:

The Kollmorgen LSM165-119-454-M-2KA is a brushless industrial motor designed with high speed and torque capabilities. It offers balanced speed and force delivery thanks to its brushless construction, which eliminates mechanical friction for efficient operation across varying loads. The absence of brushes not only reduces wear and maintenance but also enhances thermal performance, allowing the motor to sustain high output over long duty cycles. This makes the motor a good option for motion systems that demand precise force application, rapid directional changes and continuous operation.

The LSM165-119-454-M-2KA motor can sustain a continuous operating torque of 13.5 Newton-meters under rated load conditions. This level of torque ensures stable output of rotational force under load, maintaining consistent performance for extended cycles. Under peak load conditions, the motor can generate higher torque to handle the increasing load demands. Its output can reach a maximum of 51 Newton-meters for intermittent periods. This allows the motor to adjust its output based on application requirements, making it adaptable to a wide range of system requirements. The motor can respond quickly without stalling, even in applications where torque demands spike unexpectedly. This ensures consistent motion control without compromising system responsiveness or reliability.

The upper limit of electrical current that this motor can safely draw during peak operating conditions is 70.7 -amp. This high current facilitates strong torque and speed performance during peak load conditions, providing the additional power needed to handle enhanced load demands. The motor comes equipped with a holding brake that helps to simplify operational safety by facilitating safe position holding when the motor is not in operation. The brake is rated for 24 V, making it compatible with industrial power supplies in typical automation settings. This simplifies integration and setup.
