Product Description:

This particular model KA720TXX stands out as a versatile Servo Motor for industrial domains. It is created by the Sanyo Denki company which has set an impressive standard in industrial automation and motor technology.

The KA720TXX servo motor comes as a small efficient motor with a 0.2 kW rating which enables it to operate various automation functions of moderate capacity. The rotor inertia of the motor amounts to 1.47 × 10⁻⁴ kg·m² and allows for quick responses with an added rotor inertia from the tachometer generator that contains 0.12 × 10⁻⁴ kg·m². An output shaft with a key is present to maintain a reliable mechanical link between the motor and external equipment. Electric connections through the motor's lead wires reach 1000 mm in standard length and enable different installation possibilities. Such a motor does not include an oil seal which makes it ideal for operating in environments free from oil contaminants. The K Sanmotion series motor features a protection rating of IP43 that sustains exposure to small particles and light water spray though it must avoid exposure to heavy moisture or dust conditions.

The KA720TXX motor functions at 3000rpm rated speed and runs at a speed of 5000 RPM at crucial times with its 80V rated armature voltage. The torque capabilities of this servo motor include a continuous stall torque of 0.77Nm for stable performance with a peak stall torque reaching 5.4Nm to handle brief high-torque requirements. This compact motor weighs 2.15 kilograms with a 76 mm flange diameter making it both rugged and quick to respond to position or speed needs. This motor maintains stable operation between 0 and 40 degrees Celsius of temperature in controlled settings.
