  • 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
  • Application Note - 3 Set Speeds of Operation
    DART CONTROLS DC motor speed controls can be configured for field selectable 3 set speeds of operation by connecting a. switch in the potentiometer circuit. The 3 set speeds are as follows: Valid For Models: Any DART CONTROLS motor. control with an adjustable speed. potentiometer. SCR Series: 500
  • How to Streamline Air Circuits
    linear or rotary speeds of 4 m/sec (13 ft/sec) with forces up to 20 kN (4,500 lb). Linear actuators can come in stroke lengths as large as 10 m (33 ft) and, when coupled with a closed-loop system with a servocontroller and proportional valve, they can provide multiple speed, force, and positioning
  • Integrated motor and drive includes motion controls
    by adding a complete motion controller. The MDrive42AC Plus consists of a NEMA-42 hightorque brushless motor with fully integrated drive and control electronics. The company says the control delivers high-positioning accuracy, stability at low speeds, no dithering at zero speed, high starting torque
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    Pulse Width Modulation (PWM) fan speed control methodology pulse-width modulates a fan's full-rated power supply voltage at a low frequency, typically 30 Hz. A typical PWM circuit, consisting of a transistor in series with a fan, can be small and inexpensive because it is either fully
  • Synchronizing when speed counts
    accurate position. Application-specific ICs have provided a low-cost method of creating hardware capture-and-compare circuits for position control. For basic position monitoring, quadrature encoder pulses directly control the up/down count of a position counter. A servoregister records the current position
  • Motor Control Sensor Feedback Circuits
    Sensors are a critical component in a motor control system. They are used to sense the current, position, speed and direction of the rotating motor. Recent advancements in sensor technology have improved the accuracy and reliability of sensors, while reducing the cost. Many sensors are now
  • Electrohydraulic Flow Matching: The next generation of load-sensing controls
    Advanced hydraulic controls speed machine response, eliminate oscillations, and save energy. Wheel loaders with electrohydraulic flowmatching controls use less energy than machines with conventional loadsensing controls. A major challenge facing mobileequipment designers is dealing with a large
  • Interfacing Microchip's Fan Speed Controllers to a SPI TM
    Microchip's TC642, TC643, and TC646 are the world's first integrated circuits dedicated for controlling and monitoring fan speed. The new family of fan speed controllers modulate fan speed to compensate for changes in system temperature. This means the fan runs at full speed only when necessary
