  • Sinusoidal Control of PMSM Motors with dsPIC30F DSC
    with non-sinusoidal winding distribution. generate trapezoidal back-EMF, as shown in Figure 3. Phase C. Trapezoidal Back-EMF BLDC motors are specifically. designed to be driven with square voltages synchro-. nized with the motor’s angular position. This control. method is commonly called six-step
  • Low-Cost DC Motor Speed Control with CMOS ICs
    .     Author: Scott  Sangster,. Microchip  Technology,  Inc. Four outputs drive a MOSFET H-bridge, to provide rapid motor-. speed changes and motor-direction reversal. The lower rail power. MOSFETs are N-channel devices, the upper MOSFETs are P-. INTRODUCTION. channel. All four are driven directly
  • Controlling 3-Phase AC Induction Motors Using the PIC18F4431
    . upon the load. To drive an AC induction motor, the 3-phase inverter. FIGURE 2: OPEN-LOOP V/f CONTROL. bridge is driven by a microcontroller’s PWM outputs, as. BLOCK DIAGRAM. shown in Figure 2. By changing the PWM duty cycles. in a regular manner, the PWM outputs are modulated. Speed. to synthesize
  • Application Note: Troubleshooting Step Motor Operation
    - check that the increasing rate of pulses feed to the drive is not too fast for the motor to maintain synchronism with the driven load. Erratic loading - if the driven load dramatically changes while motor is driving, it could overcome the speed/torque capability of system - try to run the motor
  • IR Drop Compensation Adjustment
    the factory to the fully counterclock. IR drop of the DC motor while under load. As load changes on a. wise, or zero position. DC motor, the armature current, "I " also changes in the same. direction, i.e., if the load increases, the armature current increas-. 3. Remove the load from the driven
  • Software PID Control of an Inverted Pendulum Using the PIC16F684

The motor is controlled by an H-bridge which is. measured other than 0° is the error or Y(t) = E(t). driven by the PIC16F684 Enhanced Capture/Compare/. In implementing
  • LightKeeper Automotive Lighting Control Module
    . AN829. HARDWARE. Output Circuits. Refer to Figure 7, Module Schematics. Three high current SPDT automotive relays are driven. by a quad 1.5A Darlington low-side driver (U1). This. Power Supply. driver interfaces the low level logic signals from the. microcontroller. The driver outputs can handle
  • New ways to measure torque
    generation of digital systems eliminates. is no need for wiring to connect an antenna,. the headache of adjusting potentiometers and. amplifier or other signal conditioning equipment. switches. These systems are completely software-. driven, and output range is factory-set. However,. The variable torque
