Overview and Setup

Introduction
The BBD series Brushless DC Motor Controllers are ideal for motion control
applications demanding high speed (100s of mm/s) and high encoder resolution
(<100 nm) operation. These new controllers offer up to three channels of high-
precision motion control in a wide range of applications, and in particular in
microscopy sample manipulation when used along with our MLS203 dual axis
scanning stage. Designed using 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 of up to 5 Amp peak
coil current.
Integrated into the apt family of products, it offers Thorlabs standard control and
programming interface, allowing easy integration into the customer’s own automated
motion control applications. These units are cable 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..
