  • Sensorless Brushless DC Motor Control with PIC16

    AN1175 Sensorless Brushless DC Motor Control with PIC16 MOTOR CONTROL Author: Joseph Julicher Dieter Peter BLDC motor control consists of two parts. Part 1 is Microchip Technology Inc. commutating the motor at the most efficient rate. Part 2 is regulating the speed of the motor within defined

  • Brushless DC Motor Control Using PIC18FXX31 MCUs

    A PICDEM TM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage

  • Low-Cost DC Motor Speed Control with CMOS ICs

    Two low-cost CMOS ICs manage a 12 VDC, current-limited speed control circuit for DC brush motors. The circuit design (see Figure 1) uses PWM (pulse width modulation) to chop the effective input voltage to the motor. Use of CMOS devices gives the benefits of low power, minimal heat and improved

  • Sensorless Brushless DC Motor Reference Design

    This reference design provides a hardware and software solution for Sensorless Brushless dc motors. This document includes complete schematics, printed circuit board layout, and firmware. The Sensorless. Brushless dc motor reference design may be used as a starting point for motor control system

  • Dc motor impersonators

    , during a 2 motor speed increase. The curve duplicates the armature current for a dc motor performing the same operation. The net effect provides dc motor control response for ac induction motors. Synchronous dc motors often top the field in high-performance motor controls. This group of motors includes

Discussions about DC Motor Control Schematic
  • Re: RC car circuit

    When your car turns either way, the two motors have an oposite polarity to one another. Find the transistor outputs from the RF decoder that control the motors and XORthem; use the gate output to control a PWM before the DC BUS (e.g. 1=30%, 0=100%). You'll need basic skills in electronics.

  • Re: Windmill Synchronization

    Typically, grid connected wind turbines are now induction generators; they produce AC, not DC. You said DC, that's why I mentioned inverters. An Induction Generator is basically a standard AC motor that is driven by the wind to above synchronous speed which turns it into a generator inste...

  • Re: Non-Reversing vs. Reversing Contactor

    Hello wjwlitespeed I list the explanation below, for 3-phase squirrel-cage rotor motors. DC and single-phase forward/reverse contactor systems all have the mechanical/electrical interlock so that only one contactor switches supply power to the motor at any time.

  • Control Board Inside the PIM for GM's Old EV1 Car

    I am looking for detailed schematics for the control brd located inside the PIM of the ev1. The PIM is the box that uses 300Vdc input (from batteries/rectifier) and converts the DC into 3 phase variable frequency AC output, to run the main motor (inductive motor). I converts DC to AC by use of a 3 p...

  • Re: 1 Phase To 3 Phase

    hiii all, to be precise, simply, capacitors wont do the job. if one can design an RC phase shift oscillator for power frequencies, it would be fine since these oscillators are used only in the audio frequency range so far as i know. and again, a possible solution may be to give the single phase...

  • Re: Implementing a 1-Pole, 3-Way Switch Via Relay

    One last thing and I'll get off the subject. I have made a rough sketch of a wiring diagram for the system I described toyou. Look at it and see if there is anything you don't understand about it. I am assuming the your PC simply closes a contact through which you can run your control voltage (I...
