Описание:
The TIDA-00774 is a 1kW drive for a three-phase brushless DC (BLDC) motor in power tools operating from a 5-cell Li-ion battery with a voltage up to 21 V. The design is a 65mm x 60mm compact drive, implementing sensor-based trapezoidal control. The design takes advantage of TI's MOSFET Power Block technology, which integrates two FETs in half-bridge configuration into a single SON 5x6 package, enabling very high power density. The design uses two Power Blocks in parallel and delivers 50-ARMS continuous (120-A peak for 3 second, 160-A peak for 1 second) winding current. The MOSFET power block with minimum parasitic inductance and the current controlled gate driver with slew rate control helps in effective MOSFET paralleling and reduces switching spikes. The current sensing is done by monitoring MOSFET VDS. The board provides cycle by cycle over current and short circuit protection.

Описание:
ESC modules are important subsystems for non-military drones and users demanding more efficient models that provide longer flight times and higher dynamic behavior with smoother and more stable performance. This design implements an Electronic Speed Controller (ESC) commonly used for unmanned aerial vehicles (UAV) or drones. The speed control is done sensorless, and the motor has been tested up to 1.2 kHz electrical frequency (12kRPM with a 6 pole pair motor), using FOC speed control. Our high-speed sensorless-FOC reference design for Drone ESCs provides best-in-class FOC algorithm implementation to achieve longer flight time, better dynamic performance and higher integration, resulting smaller board size and fewer BOM components. Sensorless high speed FOC control using TI’s FAST™ software observer leveraging InstaSPIN-Motion™ C2000™ LaunchPad and DRV8305 BoosterPack.

Возможности:

InstaSPIN-FOC™ sensorless FOC achieves highest dynamic performance. Tested up to 12,000 RPM with 3 LiPo cells High dynamic performance: 1 kRPM to 10 kRPM (electrical frequency 100 Hz to 1 kHz) speed in <0.2 s to provide high performance yaw and pitch movement Fast speed reversal capability for roll movement Longer flight time due to improved efficiency of FOC over block commutation Higher PWM switching frequency, tested up to 60 kHz to reduce current/torque ripple with low inductance / high-speed motors, and to avoid interference with ultrasonic sensors Fast time-to market due to InstaSPIN-FOC’s automatic motor parameter identification: auto-tuning sensorless FOC solution Motor temperature estimation from winding resistance changes to protect motor from damage during temporary overload conditions
