Brushless DC servomotor reaches a new performance class

Faulhaber announces the introduction of a new brushless DC servomotor to
their extremely powerful BP4 product family. Available in Australia from ERNTEC Pty Ltd, the new brushless DC servomotor 2264…BP4 offers an outstanding ratio
of torque to size and weight, while the miniature drive comes with integrated
sensors and a wide speed range.

The 4-pole motor achieves a torque of 59 mNm with a weight of just 140g
and a diameter of 22mm. The DC servomotor also reaches up to 34,500 revolutions
per minute, thanks to the innovative segment winding of the coil, which was
developed for the brushless DC motors of the BP4 family. Given the overlapping,
nested, individually wound segments, an especially large amount of copper can
be accommodated in the coil.

The compact coil in the servomotor leaves sufficient room for a
resilient shaft with a diameter of 4mm and suitable bearings. Key benefits also
include low inertia, making the motor well suited for dynamic start/stop
operation; overload resistance; longer service life than standard DC micromotors;
and wide operating temperature range of -40 to +125 degrees Centigrade.

Optionally integrated analogue Hall sensors can replace an encoder in
the majority of applications and determine the position of the output shaft
very precisely. Compatible optical and magnetic encoders are also available for
high-precision applications.

Faulhaber’s new brushless DC servomotors are ideally suited for
industrial automation and can also be used as handpieces for electric tools
such as electric pruning shears and screwdrivers, motorised instruments for
surgery, grippers and robots, and also for aerospace or active prosthetics.

Additionally, Faulhaber is introducing a drive with integrated motion controller
to its family of motors. The 3274…BP4, considered the most powerful motor in
the family, is now also available as a motion control system. This combines the
brushless high-performance motor with control electronics in an extremely small
space, creating a highly dynamic drive system for complex positioning tasks
directly in the automation environment.

Faulhaber specialises in the development,
production and deployment of high-precision small and miniaturised drive
systems, servo components and drive electronics with output power of up to 250 watts.
The product range includes brushless motors, DC micromotors, encoders and
motion controllers.
