Product Description:

The AM8552-0J21-0000 is a permanent magnet-excited motor designed for ultra-smooth motion in automated systems. Its frameless design allows direct integration into mechanical systems, ensuring compact assembly and optimal use of space within machinery. This configuration eliminates the need for additional couplings or housings, enabling more precise alignment and reducing overall system inertia. This motor is designed to be compatible with various power supply setups, operating efficiently at 100 to 480 V AC. This versatile range allows the motor to be deployed across various global regions in both low and high-voltage systems. This helps to simplify integration and enhance adaptability across different operational environments.

This motor comes in a flange-mounted design that conforms to the IM B5 mounting standard. This construction layout allows the motor to be securely fastened via its front face to a machine or housing, ensuring enhanced alignment precision in different orientations. The motor is suited for low-noise environments thanks to its fanless operation which keeps acoustic noise output at moderate levels. It uses natural convection cooling to dissipate heat during operation. This low-maintenance passive cooling is ideal for applications that require durable performance. The motor features built-in feedback for enhanced precision and reliable operation.

The AM8552-0J21-0000 supports a peak current of 33.6 A, which provides the capacity needed for high torque output during peak load conditions. Under nominal conditions the motor provides 8.2 Nm of torque but is capable of a maximum of 35.0 Nm when load conditions are elevated. The motor’s rated speed of 4000 RPM, maintains steady rotational velocity across application demands, supporting fast and efficient system performance. The motor supports operation in settings with an ambient temperature range of 5 to 40°C.
