Application

The digital 3-phase current servo amplifiers BAMOBIL D3-I as component (BDM) in combination with the motor provide a 4-quadrant drive which can be used in both rotation directions for drive operations and brake operations with energy feed-back. According to the installed parameter components the amplifiers are suitable for EC synchronous motors, ac asynchronous motors, or dc motors.


The BAMOBIL D3-I can be used as position amplifier or torque or speed amplifier. The speed actual value is generated in the encoder unit (resolver or others) or internally generated (without sensors). It is necessary to provide an encoder system for wide control ranges and high control dynamics.

Design

Application in all kinds of vehicles, machines, and installations for all types of industrial use with a drive power of 18kW, especially as 4Q-servo-drives for highly dynamic acceleration and braking cycles, for a wide control range, for a high efficiency, for small motor dimensions, for a uniform, accurate and smooth running, to be used for the speed or torque control or combined speed/torque control incorporated within or independent of position control loops. Used for drives with constant speed as in conveyors, spindle drives, pumps, transversal or longitudinal pitch drives, synchronous multiple motor drives. Synchro-servo-drives are more compact than other electric drives.


They are used in battery-driven vehicles such as electric vehicles, electric boats, forklifts, transportation systems as well as battery-supplied machines and installations such as assembly machines, metal processing machines, XY cross tables, food processing machinery, robots and handling systems, conveyors, stone working machines and for many other battery-supplied industrial applications.
