Electronic enthusiasts, developers and makers searching for a modular sensorless BLDC motor controller, may be interested in a new piece of hardware created by Igor Chekhovtsov and this week launched by the Kickstarter crowdfunding website. The open source sensorless BLDC motor controller offers a modular system that includes a Texas Instruments microcontroller MSP430FR5949. To learn more about it specific features and functionality watch the demonstration video below.
The motor controller is now available to backfire Kickstarter with pledges starting from $19 for the processor module. If the Kickstarter campaign is successful worldwide shipping is expected to start during April 2018 and comes complete with open source firmware. The modular design also allows you to independently control each module and use them in different systems. The modules can also be changed or updated without affecting other connected modules, providing an easy way to expand and enhance your project as you go.
The system comprises of three modules which take the form of a Processor Module (PM) – MSP430FR5949 an Application Module (AM) offering the analog part of BLDC motor controller and the Debug Module (DM). Specifications for the Application Module include
3.3…8.4V and up to 6A (12A MOSFETs), current Sense Amplifier with gain 50, current Sense Resistor – 1/4 watt, 0.01 ohms, 1%, power pads, remote speed control pads (for 1…2 ms PPM, 0…100% duty cycle) and a small form factor measuring just 1 x 0.5 inches in size.
