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.

Frequently Asked Questions about AM8023-0E20-0000

Q: What approvals or certifications does the AM8023-0E20-0000 have?

A: Based on its official table of specifications, the AM8023-0E20-0000 adheres to the standards of the following: CE, cURus, and EAC.

Q: How long does it take for the AM8023-0E20-0000 to safely cool after operation?

A: After operation, it is best to let the motor cool for at least five times its thermal time constant. For the AM8023-0E20-0000, this means a total resting period of 80 minutes.

Q: What is the difference between the AM8023-0E20-0000’s standstill torque and nominal torque?

A: The AM8023-0E20-0000 has different values for its standstill and nominal torque. The standstill torque is the developed torque at the shaft during starting or locked-rotor conditions. On the other hand, the nominal torque is the achieved rotor torque when the motor is operated at a specific working condition or operating point.

Q: What supply voltage is best for the AM8023-0E20-0000?

A: The AM8023-0E20-0000’s nameplate specifies a nominal supply voltage of 400 V rms. However, like other Beckhoff motors, the AM8023-0E20-0000 functions well at a supply range of 100 to 480 volts.

Q: Does the AM8023-0E20-0000 include a blocking brake?

A: Unfortunately, the AM8023-0E20-0000 does not have a holding or blocking brake. If you are looking for an alternate product that has a blocking brake and is close to the AM8023-0E20-0000, you may want to check out the AM8023-0E21-0000 instead.

Internal Product Review

‘‘Beckhoff’s AM8023-0E20-0000 is a high-speed, three-phase servomotor, fit for highly precise microsystems and applications. During operation, the AM8023-0E20-0000 achieves thermal equilibrium at a relatively faster rate, due to its compact and brushless design.’’
