We’ve been so busy adding many great products to our site that we haven’t kept up with individual announcements, but we are especially happy to announce two new motor controllers, the Jrk 21v3 and Jrk 12v12. These are second-generation versions of our original feedback controllers (SMC03A and SMC04A) that you can use to make your own servo systems.
Both units can handle voltage transients to 40V.
These units have many improvements over the originals, but one of the most exciting is the addition of the native USB port, which allows these already flexible motor controllers to also function as general-purpose USB motor controllers that greatly simplify motor control from a computer. The controllers can do open-loop motor control (where you specify the power to the motor), closed-loop position control with analog feedback to make your own servos, and closed-loop speed control with a tachometer (frequency feedback). Control options are USB for PC-based control, analog voltage for simple potentiometers and joysticks, logic-level serial for use with microcontrollers and embedded systems, and RC pulse for radio control systems.
We’ve also made a great configuration utility that lets you easily set up the motor controllers and tune your systems.
There’s even a chart that lets you watch many of the parameters in real time!
