Product Description:

The MSM115-34-402-E2-2KA servo motor works to maintain steady control of power and current flows in automatic systems. The motor is a development of Kollmorgen and it achieves a high reputation due to its innovative designs and rapidly operating products.  

The MSM115-34-402-E2-2KA servo motor represents a high-end unit that serves precision motion requirements throughout standard industrial settings. With a frame size of 115 mm the motor works at 4000 RPM nominal speed to achieve 12 Nm peak torque for dynamic load operations. His moment of inertia of 0.00057 kg·m² permits the rotor to attain rapid acceleration and then deceleration moments that high-speed automation needs for successful operation. The series MSM servo motor includes an incremental encoder that provides positioning through its line count multiplied by 1000 measurements. A holding brake using 24 V power helps ensure safety alongside operational control in cases of power failure and stationary states. The motor weighing 7.7 kg carries a brake as an accessory but reduces in weight to 6.6 kg when this brake is detached. The motor starts functioning smoothly under temperature conditions from 0°C to 40°C in the control domain free of excessive humidity as well as corrosive materials and extreme industrial automation environments.

The MSM115-34-402-E2-2KA servo motor demands inspection of all cables and connectors to identify any damage before system start-up for maintaining safety and integrity. Different parts of the wiring system that suffer damage from insulation failures create dangerous electrical conditions that might result in system breakdown. The servo motor functions as a dependable industrial solution to meet the performance needs of high-speed applications alongside precision control features together with embedded safety systems that match normal industrial protocol.
