This DC servo motor controller can also be used with an external potentiometer or the integrated on board potentiometer. For applications with existing PWM signals available this can also be used ...

Adding to this are vector control methods that give the AC drive the capability and flexibility of a full DC motor drive. Fig. 1. Essential elements of a PWM motor drive. Fig. 1.

Motor current during the PWM off period decays rapidly through two anti-parallel diodes of Sa ' and Sb, and reverse application of bus voltage (for regeneration) ensues.

Design firm Escatec has developed a control algorithm for a sensorless brushless DC motor to be used as a surgical drill with the control precision for medical procedures. The precision motor control ...

The device's PWM functionality allows smooth motor control: With an enhanced PWM frequency of up to 25 kHz, which is outside the human acoustic range, the DC motor control is carried out without ...

– American Control Electronics (ACE) introduces the DCR300-60 and DCR600-60 Series, microprocessor based, low voltage PWM drives for brushed DC motors up to 24 and 48 VDC, respectively.

The DC power controller circuit is powered at 12V, regulated down to 8V by IC1 78L08. Capacitors C1, C2 and inductor L1 prevent noise being fed back into the power line when the load is being switched ...

The iW1700 zero-power ac/dc digital PWM controller enables low-cost, energy-efficient 120/230V-ac offline adapters and chargers requiring as much as 5W, which consume zero no-load power for cell ...

The Brushless DC Motor Market is currently witnessing explosive growth as the automotive, industrial automation, and consumer electronics sectors undergo a paradigmatic change towards energy-efficient ...

The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) measurement of winding current “allowing motor control designers to ...
