Hardware Design Considerations for an Electric Bicycle using BLDC Motor
Texas InstrumentsA traditional bicycle is a two-wheel vehicle that is propelled by the rider who delivers muscle power through pedals that rotate one of the two wheels. The rider steers the front wheel to create a force that returns and maintains the vehicle center of gravity into a stable zone whenever necessary, thus keeping the bicycle upright. An electric bicycle carries batteries that deliver electric power to a motor that is coupled to either wheel. In most electric bicycles the rider can chose to use muscle power to deliver all, part, or none of the propulsion power required to maintain an adopted travel speed. Some models even sense pedal pressure and command the motor to deliver more power whenever the rider pedals harder.

Comp Cons: Mig from 570LS31x/21x or 570LS12x/11x to 570LS04/03x Safety MCUs (Rev. A)
Texas InstrumentsThis application report provides a summary of the differences between the TMS570LS04x/03x versus the TMS570LS31x/21x and TMS570LA12x/11x series of microcontrollers.
Field Oriented Control 3-Phase AC-Motors
Texas InstrumentsThe principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the three phase system as three independent systems the control will remain analog and thus present several drawbacks. Since high computational power silicon devices such as the TMS320F240 from TI came to

Design Considerations for the DRV411
Texas InstrumentsThe DRV411 is a signal-conditioning integrated circuit for use in closed-loop magnetic current-sensor modules. The DRV411 is designed to interface with symmetrical indium antimonide (InSb) and gallium arsenide (GaAs) type Hall sensors. Symmetrical Hall elements have their input and output impedances closely matched. The DRV411 contains excitation and conditioning circuitry that significantly red

TMS320C5x DSK Analog I/O
Texas InstrumentsThe 'C5x DSK is designed to directly connect to a microphone and an 8-ohm speaker via RCA jacks. The I/O RCA jacks are directly connected to the dual A/D and D/A converter called the Analog Interface Circuit (AIC). In some instances the microphone does not generate the signal level required for the AIC to detect and convert the signal. It is suggested that a dynamic or amplified (pre-amp) microph
