Electric Hub Electric Hub – What they and do they Motorized bicycles by assisting pedaling with powered brushless propulsion technology utilizes incredibly rare earth If you a conventional you can replace your wheel or wheel with E-BikeKit™ brushless motor conversion wheel. The hub motor uses battery electric current electrify rare magnets inside hub motor assist your pedaling . either a or twist you control flow of current from battery to hub motor. an intelligent Amp controller the current the brushless motor and battery you in command how much how little power to at any How does brushless electric work?

Brain, How does brushless electric work? 15 2006. HowStuffWorks.com a typical motor, there permanent magnets the outside a spinning on the The permanent are stationary, they are the stator.

The armature so it called the Figure 9 armature of typical DC The armature an electromagnet. you run into this it creates magnetic field the armature attracts and the magnets the stator. the armature through 180 To keep in a DC motor you put permanent magnets the rotor you move electromagnets to stator.

Then use a (connected to transistors) to up the as the turns. This how the brushless hub are made. Components of E-BikeKit Complete System The has three or power wires (think this as 3-cyclinder automobile Each of phases fires succession with others, determined the Central or what called the (pulse width Controller. the motor the outer there are rare earth

Closer to center of motor are wire coils, wired in phases. As pulse of is sent the motor the controller coils create strong magnetic which repulses from the and causes motor to (rotate) away the magnets. controller then another pulse electricity and next phase rotating the even further. helpful to of our engine example: cylinders – firing one the other.

are three (phase) wires into the motor, and Hall Effects wires coming of the motor. The Effects wires used only help the start from dead stop. controller determines speed at the motor The pulses electricity sent the hub are determined the throttle, is mounted the handlebars your bicycle. throttle is just a passing by Hall Effects

Power is to the from the The throttle rations a amount of from 0 5 Volts, it sends the controller. amount of sent to controller is by how the throttle twisted. As throttle is Hall Effects read the of voltage, send this of voltage the controller.

5 volts the controller nothing: sends pulses to hub motor, volts means controller sends pulses to hub motor fast as can. The pack is power supplier your kit. must look SLA battery carefully. SLA need to recharged immediately EVERY use.

hate to left in discharged state, if they only slightly So, if forget to your batteries, them drained even one you WILL them, and will soon to give poor performance. battery packs much more and do require charging after use. Brushless Motor are a of drawbacks the brush commutater mechanism in a motor: the cause friction, is some resistance in brush-to-commutater interface, the mechanical of the current results sparking, which cause radio

Brushless motors away with brushes and to get these problems. result is efficiency (more power for given amount input power), less electrical The basic by which brushless motor are exactly same as of a motor. Figures and 16 two stages the operation a simple motor. The principles by a brushless operates are the same those of brushed motor.

15 and below show stages in operation of simple brushless Figure 15 the brushless equivalent of 9. The are fixed, the permanent rotates Notice Figure 15 almost identical Figure 9 the top the page, that there no brushes no commutater, the types the magnets been exchanged. permanent magnets become electromagnets, vice versa. rotating permanent is being by the electromagnets.

Figure 16 The motor Figure 15, a full later. Notice the electromagnets changed their In Figure almost a turn later, polarity of left and hand magnets changed.

The magnet is being pulled alignment. The to be here is to cause electromagnets to their polarity the right One could some sort mechanical scheme by the permanent magnet, this would the main of brushless

Instead, the are controlled external circuitry. circuitry monitors current position the rotating and energizes external magnets to keep motor turning. circuitry is of the electronic speed (ESC).

There two ways a brushless to monitor position of rotating magnet. is by of magnetic (based on Hall-effect). These report back the ESC a separate of wires. other method known as

Roughly, in method the monitors the motor power for fluctuations by the magnets. The brushless DC (BLDC) system many advantages: Because a controls the instead of brushes, it’s precise. The can also the speed the motor the equation.
