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...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of rotation. Continuous operation of dc motors is commonly available over a speed range of 8:1...

Recent advances in electric motors and controllers improve their speed, acceleration, controllability, and reliability, while allowing designers a wider choice of power and torque. Selecting a fractional hp dc motor is easier when you know how to handle motor constant . Guidelines used by experts...

The torque generated by the motor, and its speed of rotation, are dependent on each other. This is a basic characteristic of the motor; it is a linear relationship and is used to calculate the no-load speed and the start-up torque of the motor....

Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. The rotating speed of ac induction motors is determined by the frequency of ac applied to the stator, not the applied voltage. However, stator voltage must also drop to prevent excessive current...

...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...

Many applications call for a high start-up torque. The DC motor, by its very nature, has a high torque vs. falling speed characteristic and this enables it to deal with high starting torques and to absorb sudden rises in load easily. The speed of the motor adjusts to the load. Furthermore, the DC...
