Tech Specs – SOLO MEGA

 SOLO MEGA is a family of high-power motor controllers that are designed for high-current
applications. This product is designed to support various types of electrical motors like DC
brushed, Brushless DC and PMSM motors up to 60V with the supply voltage and the continuous
current of up to 120 Amps DC or 110 Amps RMS, this will enable SOLO MEGA to be utilized in
wide range of products and projects and eventually speeding up the developments and time to
market for its users.
SOLO MEGA can be commanded in two different ways, either by sending Analogue voltages or
PWM pulses which is called Analogue Mode, or totally by sending Digital data packets through
isolated UART, isolated USB or isolated CAN bus lines. This will give a high flexibility in terms of
system setup to the users and they can choose the best way to wire up their systems using SOLO,
The main features of SOLO MEGA are listed as below:

  • Wide input voltage supply range from 8V to 60V
    The continuous output current of 120 Amps DC or 110 Amps RMS
    Capable of controlling DC brushed, BLDC and PMSM motors

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.

Features Detail 

Closed loop speed or Torque control using Encoders or Hall-Sensors

SOLO, despite having all the features for sensorless control, offers also the sensor-based controls for highly sensitive and accurate systems, The control can be done using quadrature encoders or Hall sensors mounted on the motors. Speed Sensored VS sensorless

Field Oriented Control (FOC)

Thanks to this feature SOLO will be very efficient, robust and able to control the torque and speed with nested torque, speed and position controllers, within the heart of FOC, SOLO utilizes the SVPWM which puts the 3-phase motors into a higher dimension of efficiency and performance.


Automatic Parameter Identification of Motors

Since each electrical motor is different with the other, SOLO identifies most of the required parameters of each motor itself in less than a second, this makes you able to control your motor either in Torque or Speed control mode in the simplest and fastest way possible. In the simplest form, you can control either of the torque or speed of your motor with a single potentiometer. Of course you can use more advanced features like sending PWM or Analogue voltages or even sending packets through UART, CAN or USB which are existing on SOLO, to control each of the features or read the motor feedback in real-time.

Active Temperature Control

SOLO actively keeps track of its own temperature and tries to keep the board temperature at 80 ℃ fixed during harsh conditions by giving the maximum possible current outside while trying to keep the temperature in range, if anything goes out of control the board will shut itself down at 85 ℃ to keep the board and the components safe.
