Product Description:

The AM3012-0CB0-0005 Servomotor serves to deliver exact motion performance. This servomotor is engineered by Beckhoff that generates 0.28 Nm of rated torque in industrial automation. The motor produces 0.23 kW of power output. The motor operates at 230 V AC while it operates at a rated speed of 8000 min⁻¹.

The AM3012-0CB0-0005 Servomotor achieves mechanical velocity stability through its 8000 min⁻¹ maximum output speed range. Standstill torque of the motor reaches 0.31 Nm while operation consumes 1.51 A of current. Under peak circumstances, the motor reaches a current output of 6 A. The system makes it possible to achieve temporary performance gains that do not reduce stability levels. Real-time system operation benefits from the torque constant value of 0.21 Nm/A, which ensures dependable control. The voltage constant of the AM3012-0CB0-0005 Servomotor measures 13.3 mV/min. It has winding resistance equal to 12.4 ohms at 25°C, and its winding inductance is 9.1 mH. These specifications enable accurate current control as well as voltage stability throughout the cycling operation. The motor promotes controlled start-stop motions because of its design. The motor provides 0.0021 Nm static friction torque, which minimizes system resistance while at rest. Operation of the motor is supported through its 6-minute thermal time constant, which regulates temperature during continuous use. This motor features a six-pole schema which maintains even electromagnetic force output across all points.

This AM3012-0CB0-0005 Servomotor weighs 0.49 kg without brakes but becomes 0.69 kg heavy when considering the brake system. It suits applications that need compact space integration. Its form factor and torque-to-weight ratio support dynamic positioning applications. The motor maintains steady mechanical and electrical operations, which make it perform satisfactorily on loads with moderate inertia. The rotor moment of inertia stands at 0.031 kg·cm² until the brake integration, yet reaches 0.035 kg·cm² with the brake installed.
