Product Description

The AM8121-3F21-0000 is a high-precision, permanent magnet-excited three-phase synchronous motor introduced by Beckhoff. Designed for compact applications, it operates on a nominal voltage of 24…48 V DC, delivering reliable performance in environments where space and efficiency are critical. The motor provides a standstill torque of 0.50 Nm, ensuring smooth operation, while the rated torque of 0.50 Nm makes it suitable for light-duty applications. With a peak torque of 2 Nm, the motor can handle short bursts of high load, and its rated speed of 3000 min⁻¹ offers quick and responsive motion control.

The AM8121-3F21-0000 features a rated power output of 0.16 kW, ensuring efficient energy use. It draws a standstill current of 4.0 A and can handle a peak current of 17.0 A, making it adaptable to varying operational needs. The torque constant is 0.13 Nm/A, which allows for precise control of torque and speed. Additionally, the motor has a rotor moment of inertia of 0.134 kgcm², making it highly stable and ideal for rapid acceleration and deceleration. Its cooling is managed through convection, simplifying installation by eliminating the need for external cooling systems.

This motor also includes a resolver for feedback and a single-turn absolute encoder for precise positioning. It connects using itec® plug technology, ensuring a secure and reliable electrical connection. The motor is designed to operate efficiently in ambient temperatures ranging from +5…+40°C, making it suitable for various environments.
