Advanced drive system for industrial automation Servo systems in industrial automation fields exploits successfully the integration of each servomotor and the relative drive. The servomotors with integrated drives provide higher flexibility for automatic machine manufacturers in terms of space optimization and installation simplicity. Benefits of this distributed system include reduction in both installation time and cable and electrical cabinet costs. The integrated solution reduces the total unit size by more than 35% compared to classical servo drive solutions. In addition, the servo motor...

Machinery system configuration The new iBMD series of servomotors with integrated drive represent a successful solution for space optimization and installation simplicity in complex automatic machinery architectures. The iBMD servomotors are autonomous servo axis building blocks that allow the design, integration and operation of large multi axis systems with significant reduction of the cabinet size, drastic reduction of wiring work and significant increase of flexibility and modularity. The integration of the motor and the drive minimizes the electromagnetic compatibility sensitivity ensuring...

The Bonfiglioli servomotors with integrated drive are available in seven sizes with stall torque comprises between 2.7 - 36. rBMD servo motors with integrated drive are technically identified by their designation. This consists of a succession of alphanumeric characters, whose positions and values conform to precise rules and define the characteristics of the product. The complete designation provides a unique identification of the exact servomotor with integrated drive configuration. All motor variant and drive variant fields can assume only one value at a time. These values are selected from...

Torque-speed characteristic The permissible operating range of a brushless servomotor with integrated drive is limited by thermal, mechanical, and electromagnetic limits. The thermal limit of the servomotor with integrated drive is dependent on both the thermal class of the motor insulation system (F) and the thermal limit of the drive components. To adhere to the temperature limits, the torque must be reduced as the speed increases, starting from stall torque M0. The maximum permissible torque is then dependent on the operation mode. The characteristic curves are assigned for continuous duty...
