1 Motor control library features
• Single or simultaneous Dual PMSM FOC sensorless / sensored (Dual PMSM FOC only
when running on STM32F103xx High-Density, STM32F103xx XL-Density or
STM32F2xx or STM32F303xB/C or STM32F4xx)
• Speed feedback:
– Sensorless (High Frequency Injection HFI plus B-EMF State Observer, PLL rotor
speed/angle computation from B-EMF, only for STM32F30x or STM32F4xx)
– Sensorless (B-EMF State Observer, PLL rotor speed/angle computation from
B-EMF)
– Sensorless (B-EMF State Observer, CORDIC rotor angle computation from
B-EMF)
– 60° or 120° displaced Hall sensors decoding, rising/falling edge responsiveness
– Quadrature incremental encoder
– For each motor, dual simultaneous speed feedback processing
– On-the-fly speed sensor switching capability
• Current sampling methods:
– Two ICS (only when running on STM32F103xx or STM32F2xx or STM32F4xx)
– Single, common DC-link shunt resistor (ST patented)
– Three-shunt resistors placed on the bottom of the three inverter legs (only when
running on STM32F103xx or STM32F2xx or STM32F302xB/C or STM32F30xB/C
or STM32F4xx)
• Embedded analog features (STM32F30x only)
– PGA (Programmable Gain Amplifiers) for current sensing: support for three-shunt
and single-shunt, internal and external gain
– Comparators for over-current protection: support for three-shunt and single-shunt,
internal and external threshold
– Comparators for over-voltage protection: support for motor phases short-circuiting
mode and free-wheeling mode, internal and external threshold
• FOC hardware acceleration(STM32F30x only)
– ADC queue of context (ST patented architecture) support
– CCM (Core Coupled Memory) RAM support
– Advanced Timer structures for single shunt (ST patented) support
• Flux weakening algorithm to attain higher than rated motor speed (optional)
• Feed-Forward, high performance current regulation algorithm (optional)
• SVPWM generation:
– Centered PWM pattern type
– Adjustable PWM frequency
• Torque control mode, speed control mode; on-the-fly switching capability
• Brake strategies (optional):
– Dissipative DC link brake resistor handling
– Motor phases short-circuiting (with optional hardware over-current protection
disabling)
