SOLO aims to be a Universal Driver and Controller for various types of electrical motors. The current version can interface with DC, BLDC, PMSM and ACIM motors. SOLO is crafted with cutting edge technologies in the industry to guarantee best performances. Here are some of the technical characteristics of SOLO:
- Wide input voltage supply range (from 8V to 58V)
- The continuous output current of 32A, Max Current of 100A
- Capable of controlling DC, BLDC, PMSM and ACIM motors
- Over-current, Over-voltage, Over-Temperature, Under-voltage and Reverse Polarity Protection
- Selectable output PWM frequency (from 8kHz to 80kHz)
- Automatic self-tuning and identification of Motor parameters
- Open-loop or Closed-loop Control modes
- Speed, Torque or Position control
- Advanced Sensor-less and Sensor-based Control
- Advance Field Oriented Control
- PWM and Analogue voltage input for Controlling Speed and Torque
- USB, UART, and CAN protocols enabled
- SVPWM modulation
- Encoder and Hall Sensor Input with +5V supply
- +5V/1A (5W) output to supply external modules
- Updatable Firmware
- Heatsink mounted on the back of the board to enhance the thermal behavior
- 1820µF onboard BUS capacitance
Make mistakes, safely
No matter how skilled, we all make mistakes. In hardware projects, this means losing time and money. We designed SOLO with safety in mind. We offer protection against reverse polarity connections, output short-circuits, over-voltage, or under-voltage on your main supply input (BUS) and over-current consumptions. You now use motors with fewer worries.
For experts and non-experts alike
SOLO is easy but not simple. The experienced user will find many advanced functionalities. From sending packets through USB, UART, or CAN to use industrial state of the art technologies like Closed-loop and Open-loop, Sensored, Sensor-less, and Field-oriented control.
Simply control the speed, torque, and position of your motor’s shaft separately. Enjoy these features while SOLO automatically detects the motor’s parameters and self-tunes.
Closed Loop Sensorless Speed Control
In sensorless mode, there’s no need to connect any sort of position sensors like Hall-Effect sensors or Encoders, and this will reduce the cost and wiring of the final products alongside with much higher reliability gained due to relying only on the electrical motor itself than anything else.
SOLO in this mode offers you a very robust experience even in very harsh conditions like below when the direction of the Brushless DC motor changes abruptly but as can be seen SOLO could fix the speed on both directions immediately with a very low error margin.
Closed Loop Sensorless Torque Control
The Torque control is done totally automatically in SOLO and the users by pushing down a button can immediately start utilizing it. In the image below you can see how SOLO kept the torque constant in a PMSM motor while the load was kept varying constantly.
Advanced Sensorless control with fast Angle Estimations
Closed loop speed or Torque control using Encoders or Hall-Sensors
Field Oriented Control (FOC)
Automatic Parameter Identification of Motors
Active Temperature Control
