What is MCTK

• MCTK (Motor Control Tool Kit) is a development kit based on automotive Grade SPC5

microcontroller, to control 3-phase Permanent Magnet Synchronous Motors:

• Easy to configure and monitor

• Very flexible and customizable

• Minimize the customer support effort

• Reduced FW re-work time when moving from evaluation kits to final customer’s production HW

• FW structure easy to be ported on different SPC5 microcontroller

• Integrated into a SPC5Studio software development environment ready for further customer improvement

• Available HW demo

• with SPC560P-DISP discovery Platform and L9907-EVAL kit

• Firmware Library Based on Field Oriented Control (FOC)

• Sensored and Sensorless support

• 2 shunt topology (current sense on motor phases or legs)

Once the HW and SW are configured, use the SPC5Studio motor control configuration component for

a complete and easy customization of the Motor Control library

Generate, compile and program the binary image on the HW board

Connect live Monitor via UART, to interact with the motor control library running on MCU, to start,

stop, change reference speed, …

SPC5 Live Monitor 9

• Available over UART

• Written in JAVA

• Dashboard with basic commands, register view for advanced usage

• Robust and synchronization communication via UART

• Comm. protocol compatible with STM32 workbench

Supported Speed / position sensing• The following speed/position sensors are supported :

Quadrature encoder The rotor position information is very precise

Alignment phase is implemented (electrical angle and duration)

Tested and validated on several motors

Hall sensors Tested only with 3 sensor 120° displaced

Highly configurable

Tested and validated on several motors

Resolver Using ArcTan to calculate the angle instead of lookup table guarantee more precision

Tested and validated on maxon motor

Sensor-less Using Luenberger observer + PLL
