jb JFS Motor Run Capacitor

A motor capacitor, such as a start capacitor or run capacitor, including a dual run capacitor, is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field. It is used in air conditioners, hot tub/jacuzzi spa pumps, or forced air heat furnaces for example.
A round dual run capacitor is used in some air conditioner compressor units, to boost both the fan and compressor motors.

Run capacitors are mostly polypropylene film capacitors and are designed for continuous duty, and they are energized the entire time the motor is running.
Run capacitors are rated in a range of 1.5–100 microfarads (µF or mfd), Single phase electric motors need a capacitor to energize a second-phase winding.
If the wrong run capacitor is installed, the motor will not have an even magnetic field, and this will cause the rotor to hesitate at those spots that are uneven.
This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop, and cause the motor to overheat.

jb JFS Motor Start/Run Capacitors, have total 22 types, with CE approvals, lower MOQ support. 
Safety class: P0, Climate category: 40/85/21, Frequency: 50/60Hz. We jb Capacitors are your best choice for Film Capacitors, Motor Start Capacitors, X2 Film Capacitors etc.

Introduction of Mr. SAM BENELBAZ

French, retired, have the hobby of TUBE do it yourself; used to work in IBM as a professional 
of electronics; after that for LASER a company involved in point of sales solutions and hardware maintenance, in that position, he bought a French company sic-safco. 

Mr. SAM BENELBAZ is member of some forums in US and France, some are AUDIOASYLUM.com and DIYAUDIO.com fun withtubes. com and some others.

Original letter from Mr. SAM BENELBAZ

Dear iris,
i hope you are ok. 
I have installed the JFX capacitors last Sunday and i can now give you my impressions.

But first i have to tell you what speakers and amps i used for the test:

The speakers are YAMAHA NS1000M well known in the market and very revealing .
The amps are two american CARY tube amps model 40M using 6SL7 and EL34 tubes.
In this test the EL34 are NOS Philips EL34 of the XF2 series (the best).

The Yamaha crossover was using mainly NICHICON capacitors using metalised paper .
I did replace every capacitor with the ones you send me.
The CDs i use for the test are very good Cds , classic music and jazz mainly.
I know them very well and can hear the differences well. 

Now lets come to the findings:
The JFX have good audio imaging and you can hear obviously more details than with the nichicon .
I think this is because they are wounded very tight.
Congratulations to the worker who did the job.

At this very moment i think that JFX are very good capacitors for cross overs and with their price-sound ratio you can go to the market without any shame.

My best regards
sam

jb Has Great Support for CBB61 Motor Capacitors -- JFS-6

Motor capacitors are operation capacitors for single-phase induction motors with auxiliary winding and three-phase motor in steinmetz circuits.

Motor capacitors are self-healing capacitors, i.e. a weak point in the dielectric would become ineffective by itself since the metal coating evaporates at the weak point.

We jb produce 18 types of Motor Start Film Capacitors, with high quaity, we also offer competitive prices and short lead time, we welcome your inquiries to info@jbcapacitors.com

Below are some main applications for motor start capacitors. and our JFS-6 series motor start capacitor picture.
Household and domestic appliances.
Office machines.
Heating and ventilation techniques.
Garden and recreational equipment.
