This open source ferry robot has unique functions such as the anti-interference standing ability of a tumbler and automatic roll-up.
This reference design provides design guidelines, data, and other content for a DC 300V input BLDC motor Hall-less control circuit using intelligent power devices. It implements vector control using an MCU designed specifically for motor control.
The wind turbine is mainly 3D printed and equipped with a BLDC motor as a generator. Foldable and no larger than 2L soda bottle. Easy to replicate and low cost to manufacture.
Starfish is a pick and place machine control board built on the Raspberry Pi RP2040 microcontroller and Trinamic TMC2209 motor driver. This control board has some similarities to a 3D printer control board, but it has some unique issues to solve—including controlling solenoids and communicating with vacuum sensors. All board information is open source, and detailed explanations are provided to help you copy successfully.
ESC is the abbreviation of Electric Speed Controller, that is, electronic speed controller, or ESC for short. The author is Benjamin Vedder, so it is called VESC. You may have heard of it, which is Benjamin ESC. This project is mainly divided into several parts, VESC firmware, bill of materials, VESC hardware, and VESC tool software. It is a very complete software and hardware project, and the supporting software is also excellent.
Both software and hardware are fully open source. The control board is designed based on STM32G4. This upgrade adds a flexible I/O subsystem and expands the types of feedback encoders and peripherals that the controller can receive.
Desktop CNC machines often use stepper motors, often because they do not require position feedback sensors, thus reducing system cost. But there are situations where a position feedback sensor is needed or necessary, and the power output of a stepper motor, especially at high speeds, becomes a bottleneck for those who want a better performing machine.
STEP400 is a stepper motor driver board that can control up to 4 axes. STEP400 elegantly combines all necessary functions, from communication to motor control, into a simple and complete package. STEP400 uses Open Sound Control (OSC) based on standard Ethernet rather than specialized industrial protocols to achieve ease of use while ensuring it is reliable enough for use in art, design or any other creative application. STEP400 can be easily controlled through creative coding environments such as openFrameworks, Processing, Max, Unity or Touch Designer. STEP400 is Arduino compatible, so you can drive the motors with your own code too.
The YMFC Flight Controller and Mini Drone is a simple, affordable, Arduino programmable open source circuit board that can be used as a standalone mini drone or as a flight control for a larger (F450 size) drone device. The simplicity of its design and control, as well as its open source nature, make the YMFC ideal for educational projects and drone enthusiasts.
This BLDC motor driver board is capable of driving one BLDC motor, or one or two bidirectional DC motors (H-bridge configuration, cascaded to support a second motor) or up to three unidirectional DC motors (half-bridge configuration).
The project presented here is a bipolar stepper motor driver. It is based on the BD63731EFV chip, a low-power driver driven by a PWM signal. The project power supply voltage is 8~28V DC, and the rated output current is 3A. The input interface adopts CLK-IN drive mode, and the excitation mode corresponds to FULL STEP mode (2 types), HALF STEP mode (2 types), QUARTER STEP mode (2 types), 1/8 STEP mode, 1/16 STEP mode through the built-in DAC . In terms of current attenuation, the SLOW DECAY/FAST DECAY ratio can be set without any restrictions and all available modes can be controlled in the most suitable way. Additionally, the power supply can be driven by a single system, simplifying design.
The 5kW evaluation board represents Infineon’s inverter-level solution for high-power motor control applications such as forklifts or low-speed vehicles. This reference design demonstrates the performance of Infineon's power MOSFET family OptiMOS™ in the new TO-Leadless package in terms of parallelization and thermal behavior.
Turnkey reference design kit for low voltage, high performance, high efficiency and high speed PMSM/BLDC motor drive applications is a reference design kit using the IMC101T iMOTION controller, 2ED2304 SOI half-bridge gate driver and BSC030N04NS OptiMOS. This reference design kit showcases our thin-film SOI and advanced motion control engine (MCE 2.0) technology enabling drive speeds up to 120KRPM for low-voltage permanent magnet motors, while the inverter section is rated up to 30 V and 25 A. It has been optimized for low voltage appliances such as vacuum cleaners, fans, pumps, compressors and other low voltage motor drive applications.
