Product Description:

The 8DI330.D90450001-1 is a great performing synchronous servo motor . It is manufactured by B&R automation, a world leader in industrial automation technologies. This motor is perfect for advanced automation systems that need to be responsive and consistent. The motor was made to be precise, reliable, and able to handle dynamic motion.

The maximum speed of 8DI330.D90450001-1 servo motor is 4500 rpm, and it has 8 poles. It has a nominal torque of 1.17 Nm and a nominal power of 551W meaning it is capable of handling normal load. The voltage constant is 65.97 V at 1000 RPM. Torque constant is 1.08 Nm/A. This enables it is possible to monitor the speed decisively over a wide range. The average of the current is 1.08 A and the stabilizator of the current is 2.22 A. This makes the motor remain stable under a sudden change of conditions. The motor has excellent temperature and electrical characteristics for long term use and the stator resistance and stator inductance are 4.81Ω and 19.81mH.

The 8DI330.D90450001-1 servo motor has a starting torque of 2.4 Nm and a maximum torque of 6.12 Nm, so it can handle tough jobs. It also has a strong torque reserve for times when it is being used at full capacity. The maximal current consumption is 5.67 A, which enables rapid acceleration and deceleration. The mass of the motor without brake is 4.7 kgs while the moment of inertia is 0.95 kgr²cm. This helps it respond quickly without adding extra weight to the system. Because it was made to work with a lot of different servo drives, the motor is easy to connect to flexible automation systems. The servo motor makes motion smooth and controlled, which is important for high-precision tasks.
