ZDBL15A – 15A Sensorless Brushless Motor Controller with Analogue Speed Control with Digital Input Options


The ZDBL15 is a powerful but lightweight sensorless brushless motor controller. Sold with standard drive programme pre-programmed (or request optimisation for a specific motor or application here)

Speed Feedback

Yes, No


Constant Torque, Constant Speed

The ZDBL15A is a 15A sensorless brushless DC (BLDC) motor controller designed to be compact and deliver high performance. Running at 12-24V and offering up to 15A max current, the ZDBL15 is easy to use and can be quickly customised in a number of ways.

This version of the controller comes with a simple communications interface using a 0-5V analogue speed control, direction and enable inputs. There is a selectable speed control potentiometer (onboard or offboard) and the controller also features a pulse output. There are 2 main selectable options on this controller, namely whether to have speed feedback on or off and whether to have constant speed or torque.

Speed feedback will increase the accuracy of the speeds you are able to achieve with the ZDBL15 but the downside is that it will typically limit the top speed you are able to achieve. Constant speed or torque is fairly straightforward and can be used to get the best out of the controller in a range of applications.

Please don’t forget that we can quickly customise the firmware on this controller and also that there is also the UART version of this – the ZDBL15UART – which will enable you to gain much more direct control over the settings. As always if you have any questions please contact our team to discuss.
