- DN-53A Design Considerations for Synchronizing Multiple UC3637 PWMsPDF, 168 Kb, Archivo publicado: sept 5, 1999
The UC3637 is an extremely versatile PWM used in many motor-control and power-driver applications, so the need for synchronization often arises. For proper synchronization, a few simple design rules must be followed. These rules apply primarily to resetting the part's current-limit latches. This design note discusses several types of circuits for synchronizing multiple PWMs and presents two simple - U-102 UC1637/2637/3637 Switched Mode Controller for DC Motor DrivePDF, 350 Kb, Archivo publicado: sept 5, 1999
The UC1637 switched-mode controller for DC motors is one of several integrated circuits offered by Unitrode for motor controls. This application note presents the general principles of its operation and the circuit details that optimize its use. It includes a design that will involves not only the UC1637, but also a power H-bridge using MOSFET transistors, and a modern DC motor tachometer. Using t - U-112 A High Precision PWM Transconductance Amplifier for MicrosteppingPDF, 211 Kb, Archivo publicado: sept 5, 1999
The UC1637 is a pulse-width modulator circuit for a variety of PWM motor drive and amplifier applications requiring either unidirectional or bidirectional drive circuits. When used to replace conventional drivers, this circuit can increase efficiency and reduce component costs for many applications. However, stepping motors are incremental motion machines, and so are sometimes erratic, for example - U-120 A Simplified Approach to DC Motor Modeling for Dynamic Stability AnalysisPDF, 106 Kb, Archivo publicado: sept 5, 1999
When we say that an electric motor is a device that transforms electric power into mechanical power we say two things. First that the motor is ?and behaves as ?a transformer. Second that it stands at the dividing line between electrical and mechanical phenomena. In the case of permanent magnet motors this power transformation works in both directions so that the electrical impedance depends on
