Usual control of a SPM (Surface Permanent Magnet) motor on RA MCUs. This module implements the Motor 120 degree control (rm_motor_120_degree).
The motor 120 degree control is used to control a motor rotation in an appication. This module is implemented with using a SPM motor. User can start/stop motor rotation simply.
The motor 120 degree module has below features.
The below figure shows examples of target hardware of this Motor 120-degree Module.
The modulation factor "m" is defined as follows.
The below figure shows a state transition diagram. Internal state is managed by "SYSTEM MODE".
(1) SYSTEM MODE "SYSTEM MODE" indicates the operating states of the system. The state transits on occurrence of each event (EVENT). "SYSTEM MODE" has 3 states that are motor drive stop (INACTIVE), motor drive (ACTIVE), and abnormal condition (ERROR).
(2) EVENT When "EVENT" occurs in each "SYSTEM MODE", "SYSTEM MODE" changes as shown the table in above figure, according to that "EVENT". The occurrence factors of each event are shown below.
EVENT name | Occurrence factor |
---|---|
STOP | by user operation |
RUN | by user operation |
ERROR | when the system detects an error |
RESET | by user operation |
The below figures show flowcharts of motor 120-degree module.

This module doesn't depend on clock setting, because this module is a simple status transition process.
This module does not use I/O pins. Please set used pins on configuration of each hardware modules.
This is a basic example of minimal use of the motor 120 degree in an application.
