Product Description:

The XSM100-37-504-M-2AA is a Brushless servo motor for use in industrial automation facilities. The motor is designed to provide steady power and dependable performance in a large number of motion controlled tasks. Kollmorgen manufactures this motor so that it can be used in mechanical systems that need precise control of torque and feedback.

The XSM100-37-504-M-2AA servo motor can operate ideally under 95% humidity range. The motor generates the continuous torque of 4.2 Nm and the torque constant value of the motor is 0.79 Nm/A. The values of the electrical windings stay the same, and they are made to give torque reliably. The dielectric strength makes sure that the insulation stays in place when the voltage goes up. The motor has a high-resolution multi-turn absolute encoder that helps factory automation systems keep track of the exact position of things. The 2AA version doesn't have a shaft keyway but does have a 24VDC brake. The end of the shaft has a thread that is M5 × 0.8 mm wide and 12.5 mm deep. The shaft is made of 1144 steel, which makes it strong enough to handle practical loads.

The XSM100-37-504-M-2AA brushless servo motor can be used in places with temperatures between 0°C and 40°C, and it can be kept at temperatures between -30°C and 70°C. The motor has 8 x poles and the winding resistance is 4.61 ohms phase to phase at 25°C. The inductance of the wire is 28 mH. The servo motor can handle 2350 volts of dielectric stress. The rotational inertia of this model is 0.00011 kg•m². This XSM100 servo motor is available to order at Wake Industrial. Order now and get this motor with 1 year warranty.

Frequently Asked Questions about XSM100-37-504-M-2AA:

Q: Why does XSM100-37-504-M-2AA use 8 poles?

A: More poles improve magnetic resolution and torque smoothness. The 8-pole design supports better control at lower speeds.

Q: Does XSM100-37-504-M-2AA include a brake system?

A: Yes, it includes a 24VDC brake. This provides controlled stopping and holding torque during power loss or commanded stop.

Q: Why does XSM100-37-504-M-2AA have 96 V/krpm Ke?

A: A higher Ke ensures stable back EMF generation. This improves voltage control and overall speed regulation under varying loads.

Q: How do 4.61 Ohm windings affect XSM100-37-504-M-2AA?

A: Higher resistance limits current draw and heat generation. It ensures consistent performance and thermal stability during extended use.

Q: Why does XSM100-37-504-M-2AA use 1144 steel shaft?

A: 1144 steel offers high tensile strength and wear resistance. It supports rigid coupling and long-term shaft alignment.
