Motor capacitor
A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor). [2] Motor capacitors are used with single-phase electric

Why do motor drives have multiple bus capacitors of small value
Having multiple smaller capacitors in parallel reduces both series resistance and inductance. Higher ripple current capability, lower ESR and sometimes better form factor (eg. shorter) to fit in a convenient spot in the enclosure are likely reasons.

Why do we use capacitors in parallel with DC motors?
Sometimes two capacitors are wired in series, with the center connection going to the case to ''ground'' it at RF frequencies. For best effect the capacitor(s) should be placed on or inside the motor. In this case a capacitor has been included on the driver board. This makes it less effective at higher frequencies because the wires from the board

6 FAQs about [Parallel motor capacitors]
Why are capacitors added to Motors (in parallel)?
Why are capacitors added to motors (in parallel); what is their purpose? I've seen many motors having capacitors attached in parallel in bots. Apparently, this is for the "safety" of the motor. As I understand it, all these will do is smoothen any fluctuations--and I doubt that fluctuations can have any adverse effects on a motor.
Can a capacitor be connected in parallel?
Capacitors, like other electrical elements, can be connected to other elements either in series or in parallel. Sometimes it is useful to connect several capacitors in parallel in order to make a functional block such as the one in the figure. In such cases, it is important to know the equivalent capacitance of the parallel connection block.
What is the difference between a parallel capacitor and a single capacitor?
which means that the equivalent capacitance of the parallel connection of capacitors is equal to the sum of the individual capacitances. This result is intuitive as well - the capacitors in parallel can be regarded as a single capacitor whose plate area is equal to the sum of plate areas of individual capacitors.
What is an example of a parallel capacitor?
One example are DC supplies which sometimes use several parallel capacitors in order to better filter the output signal and eliminate the AC ripple. By using this approach, it is possible to use smaller capacitors that have superior ripple characteristics while obtaining higher capacitance values.
What is total capacitance (CT) of a parallel connected capacitor?
One important point to remember about parallel connected capacitor circuits, the total capacitance ( CT ) of any two or more capacitors connected together in parallel will always be GREATER than the value of the largest capacitor in the group as we are adding together values.
How to calculate the total capacitance of a parallel circuit?
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,
