Product Description:
The MSM165-93-204-M-0KA Servo Motor is a product of Kollmorgen's MSM Brushless Servo Motors family products. The product serves high quality automation requirements and motion control operations.
The MSM165-93-204-M-0KA servo motor has a back EMF constant of 225 measured in volts per 1000 RPM which shows the voltage it can generate per unit of speed when acting as a generator. It comes in a frame size of 165 mm which is the width or diameter of its mounting face or body. It has a 60 mH inductance which affects how fast current can change through the windings. Without overheating it is able to deliver 34 newton meter torque for short durations which is the amount of mechanical force it is designed to provide. It does not include a holding brake. The motor body has a physical length of 357 mm which is typically sizable that typically correlates with higher torque and power capacity. It is featured with a shaft that has an M8 metric thread with a 1.25 mm pitch and a thread depth of 19 mm which is relevant for mechanical coupling and ensuring proper fit with machinery.
The MSM165-93-204-M-0KA servo motor runs on voltage of 460 volts alternating current which indicates it is designed for high voltage industrial systems that is common in large automation or manufacturing setups. It is able to safely handle 24 ampere current momentarily during peak load. Its rotor has a medium inertia equal to 0.00386 kg·m²which makes it suitable for balancing fast response with good control of heavy loads without overshooting. The neodymium magnets provide high magnetic strength which makes the motor compact but powerful.
Frequently Asked Questions about MSM165-93-204-M-0KA:
Q: How does the 60 mH inductance affect motor response time?
