  • Chemical Reactivity with Brush Materials
    This chart shows the chemical reactivity with brush materials.
  • Proper Motor Brush Selection When Brush Life is a Concern
    One of the most critical parts of this type of motor is the interface between the brushes and the commutator. Poor material selection and improper design considerations can affect both the life and the performance of an electric motor. This post briefly covers the factors which contribute to brush
  • Servo Control of a DC Brush Motor
    of the PIC17C42 as a DC brush motor servo controller. It is shown that a PID (Propor-tional, Integral, Differential) control calculation can be performed in less than 200 ms (@16 MHz) allowing control loop sample times in the 2 kHz range. Encoder rates up to 3 MHz are easily handled by the PIC17C42's
  • Post-CMP Polyvinyl Alcohol Brush Testing
    Polyvinyl alcohol (PVA) brushes are used in the semiconductor process during the post-CMP cleaning stage. Different PVA brush designs can affect wafer cleaning efficiency. Ensuring proper brush-to-wafer contact pressure and contact area is crucial in achieving clean and particle free wafers
  • Brush-DC Servomotor Implementation using PIC17C756A
    This application note demonstrates the use of a PIC17C756A microcontroller (MCU) in a brush-DC servomotor application. The PIC17CXXX family of micro-controllers makes an excellent choice for cost-effective embedded servomotor control applications. Some of the benefits of the PIC17CXXX MCU family
  • Controlling DC Brush Motor with H-Bridge Driver ICs (.pdf)
    DC brush motors are increasingly required for a broad range of applications including robotics, portable electronics, sporting equipment, appliances, medical devices, automotive applications, power tools and many others. The motor itself is a preferred alternative because it is simple, reliable
  • Oceanic probes float free -- thanks to a brush-dc motor
    With the growing interest in brushless and permanent-magnet synchronous motors, one might get the feeling that the venerable brush-dc motor is on the decline. Not so for a high-tech research probe that relies on brush-dc motors to keep it afloat as it drifts along in the sea. Scientists involved
  • Brush Selection for Chain Lubrication
    brushes also act as a cleaning mechanism by sweeping away dirt accumulation and old lubricants.
