Product Description:
The MSM115-89-404-M-2KA Servo Motor designed and developed by Kollmorgen is a perfect solution for industrial automation applications. It relates to the MSM Brushless Servo Motors Series. The module is engineered for durability and system compatibility.
The MSM115-89-404-M-2KA servo motor has a 0.01195 kg·m² rotor inertia which shows its rotor is highly resistant to changes in speed. The voltage generated per 1000 rpm due to motor rotation is 225 V/Krpm which means it generates significant voltage at high speeds which affects how you drive it. It has a high inductance of 60 mH which shows its resistance to current changes which can smooths current draw but can limit high speed performance. For a short time it is able to deliver 93 Nm of maximum torque which is great for demanding loads or rapid acceleration when needed. The highest safe current the motor can handle briefly is 24 A which matches with the peak torque that is useful for aggressive moves or heavy lifting. For every ampere of current it produces 1.03 Nm torque which means more torque at lower currents that is a good sign for efficiency and precision.
The MSM115-89-404-M-2KA servo motor is featured with 6 poles which is common in servo applications and typically allow finer control and smoother motion at lower speeds. Its rated maximum speed is 4000 rpm which is decent—not ultra high but fast enough for many servo applications. Its weight is 12 kg which implies a robust, industrial grade servo motor that has a large frame and good heat dissipation. It can deliver 10 Nm torque continuously without overheating which is solid and is suitable to drive substantial loads.
Frequently Asked Questions about MSM115-89-404-M-2KA:
Q: How does high rotor inertia help the MSM115-89-404-M-2KA servo motor?
A: High rotor inertia enhances motion stability by resisting sudden speed changes. It is particularly beneficial for applications requiring smooth and controlled movement.
Q: Why is 1.03 Nm/A torque constant important in MSM115-89-404-M-2KA?
A: A high torque constant means efficient torque generation at low currents. This helps reduce heat generation and improves system efficiency.
Q: What advantage does the 6-pole configuration offer in this Kollmorgen servo motor?
A: The 6-pole setup provides better control resolution and smoother motion. This is ideal for low-speed precision tasks.
Q: How does 60 mH inductance impact the MSM115-89-404-M-2KA servo motor's performance?
A: High inductance helps reduce current ripple, promoting smoother operation. It can slightly limit very high-speed dynamic response.
Q: Why is 4000 rpm considered optimal for this servo motor?
A: 4000 rpm offers a balance between speed and control. It ensures compatibility with many automation applications requiring mid-range speed.
