Advanced technologies for all industrial fields. These permanent magnet AC synchronous servomotors are ideal for any type of automatic machinery in particular applications with high dynamic requirements. They are particularly suited to typical applications in plastic and metal machining, packaging, food and beverage processing, winding and textile industries. They are manufactured using the “salient pole" technology. The dimensions of the motor are drastically reduced, with considerable advantages in terms of torque density, overall dimensions and dynamic performance. Thanks to the high quality...

Sensorless servo drive Bonfiglioli Agile drive matches with Permanent Magnet AC syncronous motor technology by featuring a sensorless control of these motors without feedback. Standard applications that are sensitive to dimensions and energy saving will first benefit from Permanent Magnet AC synchronous motors sensorless driven by Agile. the motor shaft from measurements of the current absorbed by the motor. By combining analytic techniques to reconstruct the electrical status of the motor and functional analysis of its magnetic circuit, Bonfiglioli Agile drives provide effective speed and torque...

BMD servo motors 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 configuration. The designation is made up of two main parts, containing fields for: - BASIC variants - OPTIONAL variants Both the BASIC variant and OPTIONAL variant sections of the designation are divided into fields, each of which defines a particular design feature of the motor. All basic variant...

Concerning BMD servomotors, fixing dimensions for coupling motor with other transmission components (gearboxes, joints, ...) is named Mechanical Interface. Therefore the Mechanical Interface is a part of the motor and includes both flange and shaft univocally defined by its geometrical dimensions. The flanges and the shafts of BMD are described by fixed geometrics according to standard IEC 60072-1. Mechanical interface of servomotor Transmission member Mechanical interface: connection flange + trasmission shaft. According to IEC 60072-1, the interface geometry is defined by quantities D, E, P,...

Dimensions and tolerances of shaft extension, key and flange are in accordance with IEC 60072-1. Shaft extension features an axial threaded hole in accordance with UNI 3221, DIN 332. Tolerances for the different parts are reported in the table. Component Dimensions Tolerance

Torque-speed characteristic The permissible operating range of a brushless servomotor is limited by thermal, mechanical, and electromagnetic limits. The thermal limit is dependent on the thermal class of the insulation system (F). 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 S1 and intermittent periodic duty (S3-20%, S3-50%). A transient, high overload capacity up to Mmax is provided. The speed...
