R2AA18450HXR94M

Product Description:

Sanyo Denki manufactures the R2AA18450HXR94M servo motor. The main job of the servo motor is to provide controlled and precise rotation, and the combination of electrical and mechanical principles achieves that. In this case, the “Rated Output” of 2.5kW means the power the motor can sustain. This is basically a measure of how fast the motor converts electrical energy into mechanical work. In other words, it’s the motor’s ability to do tasks that require a lot of force and speed. The “Voltage” specification of 200V means the electrical potential difference required for operation. This voltage level affects the motor’s performance characteristics like torque-speed curve and overall efficiency. One of the most important aspects of a servo motor is its ability to position accurately, and that’s where the “Encoder” comes in. The R2AA18450HXR94M uses a “17-bit battery-less absolute encoder (HA035)” with a resolution of 131072. An encoder provides feedback to the motor’s control system so it can determine the motor’s exact angular position.

A 17-bit encoder means each rotation is divided into 2^17 (131072) positions, which is high positioning accuracy. The fact that it’s “battery-less absolute” means it can retain its absolute position even when power is lost, which removes the need for battery backups and increases system reliability. This is critical in applications that require very high positioning accuracy and where returning to a known position is a regular event. The “Maximum Continuous Torque” of 450 kg·cm means the rotational force the motor can sustain. Torque, in physics, is the rotational equivalent of linear force. This torque value means the motor can handle high-load applications without stalling or degrading performance. The physical construction of the motor, including the strength of the magnets and the design of the windings, affects this torque capacity. Then there’s the “Brake Option,” which, as listed, can either have a brake or not have a brake.

A motor brake is a key safety feature in many industrial automation systems. With the brake applied, the motor shaft will be held in a fixed position, resisting rotational force. This can be used in vertical applications to prevent loads from falling when the motor is powered off. The motor has “CE Marking and optional UL Compliance,” which means it complies with international safety and quality standards. CE marking means the product meets European Union safety, health and environmental requirements, and UL compliance means it meets US safety standards. These certifications are important to ensure the motor’s reliability and safety in various industrial applications.
