How to work out which capacitor I require to run a

Its a bit of a kludge to use a single value capacitor, as during start, or heavy load, the motor will present a lower impedance, and the phase shift is too high, (as it gets nearer the 90 degees you get with a capacitor and a

Can you use capacitors that are rated for much higher voltages

For hobbyist projects, I try to buy capacitors with a 50V minimum rating, so I can use them in most of my circuits, even though most of the caps will only be used in 5V or 3.3V circuits.

Can the small voltage output from a dc hobby motor (used as a

$begingroup$ Be aware (you may be) that you can step up one or other of voltage OR current but you cannot "step up" energy or power. If the input power is not enough to supply the load requirement, adjusting voltage will not help. | That said, a small motor will usually provide enough power and you need to change the voltage.

555 timer and 3V DC motor | Electronics Forums

Hello, I''m building a little 555 timer circuit that turns a small geared 3VDC motor on for an as yet undetermined time (estimated max 15seconds). When calculating the RC for the timing is it best to keep the capacitor at or under 1uF with larger resistor values so as to

Value of the capacitor parallel with the DC motor.

The capacitor you use should be rated for at least 2x the voltage the motor is running off on. 4x is preferrable. Otherwise the voltage spikes from the motor will destroy your capacitor very quickly. Here are some things you should know:-If you just need the capacitor to filter out motor noise, they can be quite small.

capacitor

Popping capacitors across a brushed motor reduces noise from the motor, but to a fast PWM edge, those lovely capacitors can be a horrible load, so you should add some inductance into the PWM output stage to make the load more palatable. Also note that an X2Y capacitor makes use of the motor case as its ground - but that in turns means the case

Motor Capacitor Size Calculator

A start capacitor provides an extra torque boost to help the motor start, while a run capacitor helps maintain motor efficiency during continuous operation. What is the rule of thumb for capacitors? A rule of thumb is that for run capacitors, you can use 0.1 to 0.2 μF per horsepower, and for start capacitors, 100 to 200 μF per horsepower.

High-voltage capacitor in a low-voltage system

If you look (wikipedia etc.) at how capacitors are constructed, and the factors that determine capacity and voltage-tolerance, that may help explain why the different ratings exist and why using a 1000v capacitor in your 5v circuit may be just as poor an idea as using a 3v one.
