Product Description

The SD-B4.092.020-00 000 Bosch Rexroth permanent-field servomotor is an integral aspect of the manufacturer's Servodyn system. This motor is suitable for applications with position and velocity servo loops along with an inverter. The product is designed such that it can perform electronic commutation. This device has a brushless tacho for velocity feedback. The unit has the ability to deliver maintenance-free operation because of the brushless nature of its tacho. It supports the dismantling of only its tacho board by the user if required. This motor has a nominal speed rating of 2000 rpm.

The product comprises ferrite permanent magnets in its rotor. This device has a peak torque that is three times its rated torque. The unit is not a good choice for applications that rely on stringent requirements. Its true running tends to get impaired by rotationally asymmetrical misalignment. This motor has an aluminum securing ring around its plastic connectors. The product should have the protective covers of its connectors firmly secured in place during the transportation phase. This device has no customization. The unit is equipped with a flange of size 142 mm. It is protected against thermal overload by means of a NTC thermostat integrated in its windings.

This servomotor comprises a commutation sensor that is repsonsible for the commutation of the phase currents of the connected inverter. The product has no built-in encoder or second shaft end. This device can support up to 60 N axial force with IM V3 mounting. The unit is stopped in the shortest time with the maximum current by the braking resistors in an emergency stop situation to avoid the coasting of the feed axes. It supports three kinds of braking contactors.
