DMOS DRIVER FOR THREE-PHASE BRUSHLESS DC MOTOR. The L6235 is a DMOS Fully Integrated Three-Phase Motor Driver with Overcurrent Protection. Realized in MultiPower-BCD technology, the device
combines isolated DMOS Power Transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a three-phase BLDC motor including: a three-phase [...]

The low speed system’s hardware setup is composed of a permanent dc motor, driving circuit, servo amplifier (PWM), a mechanical frame as an inertial load, interface circuit (A/D and D/A), an encoder for position sensing, and a personal computer (PETIUM I 133) is used as the programming environment, using Borlandc31 as programming language for the [...]

The UCC3626 motor controller device combines many of the functions required to design a high-performance, two- or four-quadrant, threephase, brushless dc motor controller into one package. Rotor position inputs are decoded to provide six outputs that control an external power stage. A precision triangle oscillator and latched comparator provide PWM motor control in either voltage- [...]
