Boosted servomotor

Dunkermotoren’s BG65 SDC-servomotor is an enhanced version of the BG65.

The output power of the latest model is more than double that of its predecessor, with the same footprint.

The existing synthetic material, ring-bound magnets are replaced by sintered Neodym iron boron segment magnets.

The use of these anisotropic magnets permits maximum directional efficiency to the individual magnetic poles especially in the transition zone when changing polarity.

Combining the motor design with these magnets gives a rise in output power from 84 to 190 W.

The torque increase is double, from 26 Ncm to 52 Ncm at almost identical nominal speeds and the efficiency also improves with all BG65 S variants, by about 15%.

The earlier motor was available in three lengths of 115, 140 and 165 mm. The longest version in the latest series becomes redundant with lengths of 115 and 140 mm in various voltages.

The motors can be equipped with different electronic functions, including an integrated speed controller for 4Q operation. The next configuration level is the integrated 4Q servo controller with PC software.

For customised projects with more demands, the integrated programmable motion controller (MI) is available. This enables the motor to execute standalone, master-slave functions.

Further components include planetary gearboxes (up to 160 Nm) and worm gearboxes (up to 30 Nm).
