Product Description:

The MSM115-34-404-S-0KA servo motor is manufactured by Kollmorgen, which is designed for precise motion control in industrial automation. The torque constant of 0.95 Nm/A and the back EMF constant of 115 V/kRPM ensure that it converts power efficiently.

The MSM115-34-404-S-0KA servo motor consistently operates under load, with a continuous stall current of 4.5 A and a maximum speed of 2800 rpm. The precise acceleration and deceleration can be achieved because of its rotor inertia of 0.005 lb·in². With its integrated sin/cos feedback, the servo motor can precisely position itself and control its motion with high-resolution encoder inputs. It uses a 16 AWG motor power line to guarantee efficient and steady power delivery. Because it can withstand non-condensing humidity levels between 5% and 95%, it is ideal for use in extremely demanding environments. And as per the requirements of IEC68-2-27, the servo motor can endure mechanical shocks up to 15 g for 11 ms. The 6.6-kilogram servo motor keeps its small appearance despite the lack of a retaining brake. For every 300 meters beyond 1500 meters altitude, the torque production decreases by 3%.

The MSM115-34-404-S-0KA servo motor is designed to withstand tough industrial environments with precision and durability. An 11 ms mechanical shock with 15 g of force is permissible according to IEC68-2-27. For more accurate control of dynamic motion, use the built-in sin/cos feedback mechanism for position detection. The motor functions properly in a temperature range of 0 to 50 degrees Celsius. The servo motor maintains full performance up to 1500 meters. These attributes assure long-term stability, making it ideal for complex industrial automation systems with high-performance and dependability requirements. In motion-critical systems, the motor ensures accurate control and longevity.

Frequently Asked Questions about MSM115-34-404-S-0KA:

Q: How does MSM115-34-404-S-0KA manage thermal load?

A: The 0°C to 50°C operating range maintains motor stability. It prevents performance loss under typical operational temperatures.

Q: Do altitude limits affect MSM115-34-404-S-0KA output?

A: Yes, above 1500 m, a 3% torque derate applies every 300 m. This protects performance at elevated altitudes.

Q: Why does MSM115-34-404-S-0KA lack a brake?

A: The no-brake design reduces system complexity. It is suitable for systems not requiring static holding torque.

Q: Does MSM115-34-404-S-0KA support wide humidity levels?

A: Yes, the motor functions between 5% and 95% non-condensing. This makes it suitable for variable moisture environments.

Q: How does 16 AWG cable benefit MSM115-34-404-S-0KA?

A: The 16 AWG cable supports safe current delivery. It ensures minimal voltage drop across standard motor wiring distances.
