Product Description

The AM8021-4BH0-0000 is a standard three-phase servomotor manufactured and released by Beckhoff under the AM motor series line. Having a flange length of 58 mm and a motor frame length of 111.5 mm, the AM8021-4BH0-0000 excels for compact applications requiring a high-power density servo motor. The AM8021-4BH0-0000 incorporates a radial shaft sealing ring on its drive side, along with a dedicated sealing air connection. The radial shaft sealing prevents intrusion of both foreign particulates and low-pressure liquid jets on the shaft side. The AM8021-4BH0-0000’s plain and smooth shaft offers versatility and convenient load attachment for various load types.

The AM8021-4BH0-0000’s multi-turn encoder incorporates Beckhoff’s one cable technology (OCT), allowing it to measure rotor position and revolution for lesser wiring costs. The AM8021-4BH0-0000 also uses a 24-bit SIL-2 motor encoder that is crucial for very precise applications. Since the AM8021-4BH0-0000 employs no blocking brake, its total mass is just one kilogram. During standstill motor operation, the AM8021-4BH0-0000 outputs an equivalent torque of 0.5 Nm at a current rating of 0.85 A. At most, the AM8021-4BH0-0000 can operate safely at a maximum voltage of 480 V and at a maximum mechanical speed of 12,000 rpm. Aside from its maximum speed and voltage rating, the AM8021-4BH0-0000 can also safely transmit a maximum torque and current of 2.68 Nm and 4.9 A, respectively.

Depending on the supply voltage, the AM8021-4BH0-0000 exhibits different operating parameters. At 480 V, the machine outputs a torque and power of 0.5 Nm and 0.47 kW at a nominal speed of 9000 rpm. As the supply voltage decreases, the machine’s working speed also decreases. For 400 V supply input, the corresponding speed, torque, and power are 8000 rpm, 0.5 Nm, and 0.42 kW, respectively.
