The key of HC32M140 is characteristic
HC32M140 series is a chip that dominates a design technically in the light of electric machinery. The 32 position control of kernel of chip use Cortex-M0+ implement, 48MHz of top job frequency. Inside buy 1 12 ADC(1Msps) , amplifier of 2 high-powered operation, 1 voltage comparator, timer of 1 advanced PWM (applicable three-phase electric machinery controls) .
L fan: The fan outside air conditioning, fan, smoke canister of wind of lampblack machine, high speed to wait
L compressor: Freezer compressor, car carries air conditioning compressor to wait
L water pump
Control block diagram
The system used the FOC that does not have sensor to control a system, apply to the drive of electric machinery of synchronism of three-phase permanent magnetism, a variety of control mode such as supportive speed control, power control, torsion control.
The system is compositive hardware sheds protection too, owe too press protection, peak value to shed protection, root mean square to shed protection, electric machinery to lack photograph protection too too, the rich protective function such as locked-rotor protection. Pass agile parameter configuration, the user can adjust protection according to product requirement sensitivity of threshold value, protection, restore time with breakdown, those who ensure the system is stable, reliable move.
HC32M140 is China a of most conductor special electric machinery dominates chip, use inside the operation amplifier of buy and voltage comparator, the user can reduce BOM cost further, reduce PCBA area. In the meantime, china most conductor also offerred PMSM without sensor FOC control is covered, pass agile parameter configuration, the user can guide quickly product, shorten the development cycle of the product.
