Product Description:

The Kollmorgen MSM115-34-402-M-0KA brushless servo motor establishes exceptional standards for industrial motion control because of its optimized 8.4 winding resistance and solid torque abilities. Engineered for challenging automation settings this motor brings together peak torque capability at 12Nm with continuous output at 3.8Nm which allows precision mechanism control to maintaining positional precision.

The ST-60 steel shaft construction enables the motor to handle heavy radial and axial loads that are typical in industrial settings and preserves its concentric operation. Although the 6.6kg lightweight frame does not reflect its high power density the product excels in engineering applications requiring optimal balance of space utilization and performance outcomes. The winding optimization produces an effective 8.4 resistance that decreases heat output during sustained operation thus maximizing energy efficiency. The motor maintains uniform operation throughout prolonged production schedules through its heat management system which includes heat protection mechanisms for critical peak usage times.

The brushless technology structure prevents commutator deterioration which leads to prolonged service durations beyond what traditional servo motors achieve. The motor aligns with Kollmorgen's full drive platform which makes it easy for system integrators to use it for new projects as well as equipment modernizations. Industrial mounting patterns together with standard feedback interfaces are integrated into the design to facilitate both mechanical assembly and electrical wiring. Avoidance of cogging torque becomes possible through advanced electromagnetic simulations which provides smooth movement at low speeds needed for precision assembly work. Predictive maintenance strategies become possible for Industry 4.0 manufacturers because the motor provides reliable operation parameters that enable their implementation. Medical device production facilities particularly benefit from this device because its wide palette of torque output rates works in tandem with precise control attributes. Modern automated facilities seeking to boost performance and sustainability should consider the MSM115-34-402-M-0KA with Kollmorgen servo drives since they offer optimized motion profiles which enhance throughput efficiency while lowering energy usage.
