Below you will find a detailed description of the technical specifications of the Beckhoff AM8131 - 0200 - 0030 servo motors:

Basic specifications

Model Naming Meaning: “AM” stands for Rotary Synchronous Servomotor; “81” is the chassis number; “31” corresponds to the specification number under this chassis number; “0200” represents a specific winding design; ‘0030’ represents a specific encoder configuration.

Mechanical Parameters

1. Dimensions

- Motor length (without shaft extension) is approximately 145mm.

- Shaft diameter is 14mm and shaft extension is 30mm.

- The mounting flange conforms to the IEC standard 60mm square flange for easy mounting to a variety of equipment.

2. Weight: approx. 3.5kg.

3. Protection level: up to IP65, which means it can effectively prevent dust from entering, and can withstand water spray from all directions without causing damage to the motor, suitable for use in more severe industrial environments.

Electrical parameters

1. Power

- The rated power is 0.75kW, which can provide stable power output for the equipment.

- The continuous blocking power is 1.2kW. 2.

2. Voltage & Current Voltage & Current Voltage

- The rated voltage is 400V (three-phase AC), which is the voltage level commonly used in industry.

- The rated current is 2.2A.

3.  Rotation speed and torque

- The rated speed is 3000rpm , which can meet the speed requirements in many application scenarios.

- The rated torque is 2.4 Nm and the peak torque is up to 7.2 Nm, which can output a large torque in a short period of time to cope with the load change.

- Stall torque is 4.8 Nm.

4. Moment of inertia: The rotor moment of inertia is 4.2×10-⁴ kg-m², which affects the acceleration and deceleration performance of the motor.

5. Cooling method: Self-cooling (IC 40) is adopted to dissipate heat through the motor's own cooling structure and air convection.

Encoder parameters

1. Encoder type: Equipped with single-turn absolute encoder, the resolution is usually 20 bits, which can accurately feedback the position information of the motor shaft.

2. Feedback interface: adopts EnDat 2.2 interface, which can transmit encoder data quickly and accurately, and at the same time supports diagnostic and configuration functions, which is convenient for users to carry out system debugging and maintenance.

Temperature and environmental parameters

1. Insulation class: The winding insulation class is F, and the maximum permissible temperature is 155°C, which ensures the reliable operation of the motor in higher temperature environments.

2. Ambient temperature range**: it can work normally under the ambient temperature from -20°C to +40°C (without condensation).

3. RELATIVE HUMIDITY**: It can adapt to the environment with relative humidity up to 95% (no condensation).

Performance Features

1. Overload capacity: with a maximum overload capacity of 3 times the rated torque, it can withstand large load shocks in a short period of time and adapt to dynamically changing working scenarios.

2. Control Accuracy: Speed control accuracy can reach ±0.0%.

- Speed control accuracy can reach ±0.01%, enabling precise speed adjustment.

- Position control accuracy is affected by the encoder resolution and system configuration, and usually meets the requirements of high-precision positioning.
