  • 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

  • Brush DC Motor Basics (.pdf)

    . The design of the low inertia rotor enables. very high acceleration and fast reaction time. Finally the linear torque-speed characteristics make the motor very easy to. drive. This article is a brief technical introduction on ironless DC motors. It is intended to help engineers to better understand

  • How to select a DC Motor

    produced divided by the torque constant. Further Considerations: The constant current operation of a DC motor produces constant output torque regardless of speed. Given a constant load (i.e. torque) the speed of a motor is solely dependent on the voltage applied to the motor. Power is the product

  • Application Note - 3 Set Speeds of Operation

  • Re: DC drive

    Motor is 90 Volts, 10 AMP. Power source is 100 Volt DC. I need a way to regulate speed because current speed is too high. I tried different options this is why I gave you different figures. This is a motor that powers a tread mill. I was hoping to get the basic schematics of a DC drive so I can re...

  • 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: DC Motor Control Issue

    The battery is floating, but posibly not the DC supply, which ground might have a potential between the drive's ground and its own negative side, this is destructive, for any components closing the circuit to the ground, like the min speed pot. (motor size doesn't affect the pot's current, that's ap...

  • 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...

    Sorry for the delay, the universe just could not get out of the way. Here's a nice simple schematic of some suitable International Rectifier MOSFET parts suitable for your motor control job. You will require four of these circuits to operate two bidirectional DC motors. These will go betw...
