Chapter 2 Overview and Setup
2.1 Introduction
The BBD30x is a family of three Brushless DC Motor Controllers that are ideal for motion
control applications demanding high speed (100s of mm/s) and high encoder resolution
(<100 nm) operation:
BBD301 Single Channel Controller
BBD302 Two Channel Controller
BBD303 Three Channel Controller
These controllers offer high-precision motion control in a wide range of applications,
and in particular when used along with our DDS series fast translation stages, where
speeds of up to 300 mm/ sec can be achieved. Designed using the latest digital and
analog techniques and with high-bandwidth high-power servo control circuitry, these
new controllers are capable of driving a range of rotary and linear brushless 3-phase
DC motors at 2.5 Amps continuous current (4 Amps peak), and up to 5.2 Amps
maximum in total.
It offers Thorlabs standard control and programming interface, allowing easy
integration into the customer’s own automated motion control applications. These
units are capable of being reprogrammed in-field, allowing the option of upgrading the
units with future firmware releases as soon as new programming interfaces (such as
microscopy standard command sets) are added.
