Product Description

The AM8023-0E20-0000 is another unique Beckhoff servomotor with a 23E winding designation. It belongs to Beckhoff’s exclusive AM8 motor family, boasting a neodymium permanent magnet on its rotor and brushless motor construction. AM8 motors with a 23E winding achieve a peak mechanical speed of 12,000 rpm, a standstill torque of 1.2 Nm, and a standstill current of 2.2 amperes. During operation, the AM8023-0E20-0000’s output torque approximately increases or decreases according to its torque constant of 0.55 Nm/A. For every decrease or increase of one ampere on the motor’s input, the relative change on the motor’s output torque is approximately 0.55 Nm. Like other AM8 motors, the AM8023-0E20-0000 employs convection for cooling and iTec connection technology.

When excited at a supply voltage of 400 V rms, the AM8023-0E20-0000’s shaft revolves at a rate of 8000 per minute. At this shaft revolution rate, the output power and torque transmitted to the load approach the following values: 0.84 kW and 1 Nm. With its smooth shaft, the AM8023-0E20-0000 is appropriate for several applications demanding high shaft speed. Compared with keyed motor shafts, smooth shafts are ideal for high-speed applications because the shaft keys introduce mechanical stresses that reduce the permissible speed of the motor shaft.

The AM8023-0E20-0000 offers an advanced motor feedback system via its multi-turn OCT encoder. Without a built-in blocking brake, the AM8023-0E20-0000 weighs 1.7 kilograms and has a moment of inertia of 0.38 kg (cm^2). For most AC motors, having a blocking or holding brake increases the motor’s overall dimension, weight, and moment of inertia. The rotor moment of inertia is a quantity that describes the resistance of the motor shaft from turning or rotating.
