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 [...]

Two advanced control strategies of adaptive friction Compensation For DC servomotor are presented in this paper, the first is used for The direct on-line friction compensation in the velocity control system, The second is making use of an adaptive inverse neural network controller In the position control system. Both are composed of an adaptive Compensator [...]
