BSC103 In Stock

The BSC103 stepper motor controller from Thorlabs is a powerful and versatile device that can drive larger framed 2-phase bipolar stepper motors, with or without encoder feedback, and is ideal for a wide range of applications. This three channel APT controller features a card slot architecture and can deliver up to 48V/50W peak (25W average) drive power per channel. It is also compatible with most stepper-driven nano-positioning actuators and stages from Thorlabs.

The BSC103 uses the latest high-speed digital signal processors (DSP) and low-noise analog electronics, along with ActiveX® software technology to provide high-resolution microstepping of up to three axes, with 25,600 steps per revolution for a 200 full step motor. Additional axes can be driven by connecting one or more benchtop units via a standard USB hub. The apt stepper motor controller comes with a full suite of software support tools, making it easy to configure and control.

Compared to DC servo motors, the BSC103 stepper motor provides excellent low speed performance and positioning stability. Its operation is fully configurable, with key settings exposed through the associated graphical interface panels. Motor step resolution and lead screw pitch can be set for a particular motor/actuator combination, phase currents can be limited to suitable peak powers, and limit switch configuration is accommodated through a flexible set of limit switch logic settings. For convenience and ease of use, adjustment of many key parameters is possible through direct interaction with the graphical panel.

The BSC103 stepper controller also supports encoder feedback through dedicated quadrature encoded pulse (QEP) inputs, one for each channel of operation. This provides greater accuracy and precision in positioning, making it an excellent choice for applications where accuracy is critical. One of the many benefits of the BSC103 stepper controller is its extensive software support. With USB connectivity, multiple units can be used together on a single PC, and a fully featured Graphical User Interface (GUI) panels makes it easy to configure and control. Every APT controller comes with its own APT software suite. This software is powerful and flexible, and can be used by users to control the equipment as well as for programming operations for automation purposes. APTUser and APTConfig give you the ability to modify all settings and modes from the get-go, allowing immediate and hassle-free use straight away, with no additional software development required.
