Product Description:
The Synchronous Motor 8LSA73.E1022D200-0 is a B & R Automation’s made motor which runs at a typical speed of 2200 rpm to provide effective rotational performance in long-term usage. This motor uses an operating voltage of 400 V, which makes it appropriate for typical industrial power supplies.
This motor incorporates an optical EnDat encoder that provides high-resolution feedback for accurate positioning and speed control. This synchronous motor consumes a rated current of 9.5 A, and its locked-rotor current is rated at 11.7 A to offer critical information for overload and startup currents. The nominal torque of the 8LSA73.E1022D200-0 motor is 21 Nm for favoring applications requiring consistent torque levels. During peak operation, this synchronous motor can attain a maximum torque of 26 Nm, which makes it ideal for dynamic load cycles and precision machinery that demands controlled torque output. This synchronous motor has five pole pairs to operate smoothly and generate torque efficiently. The thermal time constant of this motor is 37 minutes to keep the temperature rise within acceptable limits under extended use. This synchronous motor is rated with a thermal insulation class F at 40°C to shield windings against thermal stress and improve operation life under industrial ambient temperature conditions.
This motor is capable of operation within an ambient temperature range of -15°C to +40°C, making it suitable for installation in cold and moderately hot conditions. Its IP64 ingress protection rating protects internal parts from dust invasion and water spray in any direction, thus enhancing its ruggedness under harsh conditions. The integrated brake system of this motor runs at 24V DC with a brake torque of 32 Nm to ensure safe and reliable load holding during stop or emergency shutdown conditions. Weighing in total at 20 kg, the 8LSA73.E1022D200-0 synchronous motor provides a balanced proportion between performance and compactness.
