Product Description:

The 8LSA75.EA030D600-3 synchronous motor from B&R Automation functions by receiving controlled electrical input to generate precise mechanical motion. B&R delivers its technology innovations specifically for industrial use on a large scale with full accuracy.

The 8LSA75.EA030D600-3 synchronous motor features a moment of inertia of 74 kgcm² which ensures stable motion response and helps manage load fluctuations effectively. Its equivalent thermal time constant of 46 minutes signifies the rate within which it can achieve a thermally established state of the motor essential in heat management when the motor is in operational duty cycles. It has an electrical time constant of 18.57 milliseconds which facilitates the speedy reaction to the alterations of voltage and current. The stator inductance is 3.9 milli-henries which forms an important consideration in the electrical time response and filtering ability and the stator resistance is 0.21 ohms which is one of the sources of power loss and motor heating. Its rated current is found to be 18.4 amperes and this determines the current that will be needed to operate continuously.

The 8LSA75.EA030D600-3 synchronous motor reaches a maximum of 26.4 amperes in the short-run peak operation. The torque of 30 Nm can be used to overcome the steady load movement by enabling startup or short overload. It contains a high speed of 3000 rpm which fits in general industrial automation drive systems. It works at a standard nominal voltage of 400 V. The enclosure is IP65 which means it is dust and waterproof. The insulation rating is Class F 40 C and it supports moderate resistance to heat. This model has no holding brake and it does not use coolant.
