Product Description:
Beckhoff is the manufacturer of AM8031-2D21-0000 Servo Motor. The motor is a reliable and efficient solution for industrial automation applications. Belonging to AM Synchronous Servo Motors Series, the motor is compact and durable and is designed for an efficient motion control operation.
The AM8031-2D21-0000 servo motor can safely operate with the highest voltage up to 480 volts. Its shaft has a smooth design meaning no keyway or gears and includes a radial shaft seal for protection which contributes to the IP65 rating. It includes a 24 volts brake to hold the motor in place when power is off which is useful for vertical loads or precise positioning. The resistance of the rotor (with brake installed) to changes in motion is 0.546 kgcm². It uses an OCT (Optical Commutation Technology) multiturn encoder which means it can track position over multiple revolutions. Once power is applied, the brake takes 25 milliseconds to fully release and allow motion. It requires a 1 ampere current to maintain its position without rotation. The standard operating speed at 400V is 3000 rpm. Its IP65 rating means it is dust-tight and can withstand low-pressure water jets which makes it suitable for industrial environments.
The AM8031-2D21-0000 servo motor total weight is 2.2 kg including the holding brake. The physical body length of the motor is 129 mm which is useful when planning space requirements. For a short duration it is able to produce 6.1 nm torque which is important for overcoming momentary loads or inertia. Under standard conditions the continuous torque the motor can provide without overheating is 1.34 nm. Its brake system runs on 24 VDC which is a common and safe industrial control voltage.
Frequently Asked Questions about AM8031-2D21-0000:
Q: Why is a smooth shaft used in the AM8031-2D21-0000 servo motor?
A: A smooth shaft minimizes backlash and simplifies coupling with precision gear systems. It's ideal for high-accuracy, low-noise motion control applications.
Q: How does the OCT multiturn feedback improve the AM8031-2D21-0000 motor's accuracy?
A: The OCT multiturn encoder provides continuous position tracking, even after power loss. It enables absolute positioning without requiring homing routines.
Q: What benefit does the 24-minute thermal time constant provide in the AM8031-2D21-0000?
A: It ensures slower temperature rise during extended operation. This improves thermal stability and motor longevity in demanding industrial cycles.
Q: Why is rotor inertia an important factor in the AM8031-2D21-0000 motor?
A: Higher rotor inertia with brake (0.546 kgcm²) offers improved load stability during acceleration. It helps minimize vibration in precise positioning systems.
Q: How does the IP65 rating support industrial applications for the AM8031-2D21-0000?
A: IP65 ensures full protection against dust and low-pressure water jets. It allows the motor to operate in harsh, unfiltered environments.
