Product Description:
The SR-A4.0091.030-00.030 is a servo motor that belongs to the SR Synchronous Servo Motor series. This motor is designed for applications that require precise motion control.
The SR-A4.0091.030-00.030 synchronous servo motor has a rated speed of 3000 min⁻¹. It supports continuous operation with smooth motion and minimal vibration. The shaft of the motor measures ∅24 x 50 mm and fits precisely into compatible couplings. The motor flange size is 142 mm which ensures compatibility with standard mounting dimensions. The motor has an encoder type used in this model which is a resolver. The resolver resolution is 8192 increments per revolution and delivers an accuracy of ±10 angular minutes. The SR-A4.0091.030-00.030 servo motor has moment of inertia is 21 x 10⁻⁴ kgm² which supports a fast dynamic response. The cooling method is natural radiation which eliminates the need for fans or external cooling units. The insulation class of this model is Class F which supports high thermal endurance during long operations. The torque constant of the motor is 1.42 Nm/A. It helps in delivering consistent torque output per ampere input. The motor has a locked rotor current of 7 A and a locked rotor torque of 10 Nm.
The SR-A4.0091.030-00.030 servo motor model can be used in robotics material handling and industrial machinery. Its robust build and resolver feedback make it ideal for precision automation. The IP67 protection rating ensures total protection from dust and temporary water immersion. The motor weighs 13 kg without a holding brake and 14.7 kg with the brake installed. Its maximum length without a brake is 246 mm which makes it compact and easy to install.
Frequently Asked Questions about SR-A4.0091.030-00.030:
Q: Does the SR-A5.0460.020-10.016 support dynamic reversal applications?
A: Yes its low moment of inertia at 21 x 10⁻⁴ kg·m² allows quick directional changes for dynamic loads.
Q: How does Class F insulation benefit SR-A5.0460.020-10.016 in continuous duty?
A: It allows the motor windings to operate up to 155°C improving reliability during prolonged high load applications.
