    CHAPTER INTRODUCTION Veronte MC24 speed controller is capable of driving any type of 3-phase PMSM motor. It can be used with a wide variety of UAVs or eVTOL vehicles and also in automotive applications (Bikes, Karts, Cars).The MC24 uses FOC algorithm for motor control together with MOSFET technology.

    Careful! The system slowly discharges the voltage on the input terminals when the battery is Warning: disconnected. Capacitors may remain charged unless enough time has passed. 2.2 Requirements To dissipate the heat from the MC24 properly, there is a need to provide 16m/s of air speed against the heatsink.

    CHAPTER THREE TECHNICAL 3.1 Electrical Specifications Table 1: Electrical Characteristics Type Specification Voltage 60-120DC Cont. Current (rms at battery input) 5 - 200A Peak Current (<5s) 400A Maximum speed (1 pole) 600000 ERPM PWM frequency 10 kHz Weigth 2430g This is the main power input for the secondary part of the driver. It must be powered with a voltage of 8 to 20V. The consumption of this pin also depends on the loads connected to 5V pin.
  • Page 12 NTC/PTC sensor. ERROR_SIGNAL This signal indicates if there is an error within the MC24. A positive voltage of 3.3V means that there is no problem. SIN/COS_SIGNAL These signals are those dedicated to the SIN / COS type analog sensor. There is a 100K ohms resistor to act as divider so the maximum voltage on the pin does not exceed 250mV.

    MC24 3.3 System Diagram 3.4 FOC (Field Oriented Control) Background In order to achieve better dynamic performance, a more complex control scheme needs to be applied, to control the PM motor. With the mathematical processing power offered by the microcontrollers, we can implement advanced control strategies, which use mathematical transformations in order to decouple the torque generation and the magnetization functions in PM motors.

    MC24 As it can be seen, there some key pieces in this algorithm: 1. Park/Clark transform: These output a two co-ordinate time invariant system and a outputs a two co-ordinate time variant system respectively. As mentioned before, this is part of the process of getting two scalar values from a three phase time dependent system.
