Product Description
Universal Motor Driver P2 Add-on Board Overview:
The Universal Motor Driver P2 Add-on Board was designed as an accessory for the Parallax Propeller 2 eight-core microcontroller. It is compatible with standard P2 dual-port accessory headers found on the Propeller 2 Evaluation Board (#64000), P2 Edge Module Breadboard (#64020), and P2 Edge Mini Breakout Board (#64019).
This 4-phase motor driver add-on supports experimentation and development with many motor types, including brushed and brushless motors. For example, it could support a single brushless 3-phase BDLC motor, a 4-phase stepper motor, or two standard brushed (2-wire) DC motors. It is the recommended motor driver for the 6.5″ Hub Motor with Encoder.
For example, it could support a single brushless 3-phase Hub Brushless DC (BDLC) motor, a 4-phase stepper motor, two brushed bi-directional DC motors or four brushed uni-directional DC motors. With a 3-phase motor, both sinusoidal 180° and classic 120° drive techniques are supported.
The open design and standard 0.1” connectors allow the Universal Motor Driver P2 Add-on Board to be used with other microcontrollers as well.
Features:
- Universal 4-phase motor driver using four UCC27211D MOSFET drivers
- Phases can be controlled individually or in groups to support many motor types including single or 3-phase motors, single/dual DC motors or 4-phase stepper motors
- Sinusoidal 180° or classic 120° drive topology
- Each phase allows individual control of High and Low sides
- High and Low sides protected against simultaneous activation
- On-board Hall effect sensor connector for motor control feedback
- Common current feedback signal for motor control and over-current protection
- Independent voltage feedback signals for each phase, for motor control and over-voltage protection
- Under-voltage protection built into the MOSFET drivers
- High-current spring terminal connectors for quick and robust connections to high-current motors
- Two grounded 0.125 inch (3.2 mm) mounting holes
- PCBs assembled, tested, and completed in Rocklin, California
