| Dimensions [mm] | How big the unit is — given as Length × Width × Height in millimetres. |
| Weight [g] | How much the unit weighs in grams, without any cables or mounting accessories. |
| Casing Options | The different housing styles available, such as open-frame for tight builds or an enclosed case for better protection. |
| Firmware | The firmware framework for which the ESCs are made. |
| Connectors | These describe both the power connectors and the logic connectors. Usually, the logic connectors are JST Connectors and the power connectors are screw terminals. This way you can attatch the DC supply and the phase wires via cable lugs. |
| Supported Sensors | These are the supported position sensors technologies for your motor. Most medium size motors come with Hall-effect sensors (HALL sensors), but some smaller, high RPM motors might not feature any sensors at all. Very large motors tend to feature encoders. |
| Logic output voltage [V] | Our ESCs provide an internally regulated low-voltage rail for any accessory electronics in your application. This is the "logic output", as it is mostly intended for sensors and other secondary logic. This parameter describes the voltage of the logic supply. |
| Logic supply current [A] | This describes the logic supply current capability. Surpassing this current limit may interfere with the function of the drive, so be careful! |
| Minimum input voltage [V] | The lowest voltage the controller can run on. Going below this may cause it to behave unpredictably or shut off. |
| Maximum input voltage [V] | The highest voltage you should ever feed into the unit. Exceeding this risks permanent damage. |
| Maximum battery current [A] | The maximum possible current the controller will draw from your power supply (usually the battery). |
| Maximum motor current continuous [A] | This is the amount of current the controller can send to the motor continuously. It is highly dependant on your cooling setup.
Some of our controllers have a seperate given value for this, because their internal design limits this value below the peak current even if perfect cooling was provided.
For the controllers which don't have any continuous rating, close to the peak value can be achieved continuously with adequate cooling. |
| Maximum motor peak current [A] | This is the maximum amount of current the controller can handle for a short time. This amount of current is mostly defined by the transistors used in the design, while the duration is related to the cooling method used. |
| Maximum duty cycle [%] | The maximum duty cycle defines the maximum available output voltage for the motor and therefore the maximum motor RPM. This value is usually well above 90%, which is sufficient for most applications. |
| Current sensor type | The method used to measure how much current is flowing through the motor phases. There are mainly two techniques, which are "phase shunts" and "low side shunts". Phase shunts are the de-facto gold standard for current measurement, as they measure the phase current directly where it is produced. While offering very good performance, the phase shunt measurement bears technical difficulties, which make it a more expencive technique. Low-side shunts are a simple, indirect measurement method, which is therefore often used in cost-optimized designs. |
