Also have a look at my post on motor stall torque, which is at least a starting point. OK, that was kind of a bad pun. These are the oldest and among the simplest designed motors.

They are what you made in Science class in school — if you had a cool teacher — with two magnets, some coils, and the way they work is to use the coils as electromagnets which quite literally bounce off of the fields of the permanent magnets.

They have pretty good starting torque characteristics.

AC motors are brushless, and can either use a magnetic field generated by coils, or by permanent magnets. There are two main types of AC motors, depending on the type of rotor used. The first type is the induction motor or asynchronous motor; this type relies on a small difference in speed between the rotating magnetic field and the rotor to induce rotor current. The second type is the synchronous motorwhich does not rely on induction and as a result can rotate exactly at the supply frequency or a sub-multiple of the supply frequency.

The magnetic field on the rotor is either generated by current delivered through slip rings or by a permanent magnet PMAC. This is probably the most confusing part for anybody but an electrical engineer. The two types are virtually identical in design and structure.

BLDC is trapezoidal. PMAC is sinusoidal. What that means, I guess, will have to be the topic of another post when I actually have it figured out, maybe. In series motors stator windings and field windings are connected in series with each other. As a result the field current and armature current are equal.

Heavy currents flow directly from the supply to the field windings. In a series motor electric power is supplied between one end of the series field windings and one end of the armature. When voltage is applied, current flows from power supply terminals through the series winding and armature winding.

The large conductors present in the armature and field windings provide the only resistance to the flow of this current. Since these conductors are so large, their resistance is very low. This causes the motor to draw a large amount of current from the power supply.

When the large current begins to flow through the field and armature windings, the coils reach saturation that results in the production of strongest magnetic field possible. The strength of these magnetic fields provides the armature shafts with the greatest amount of torque possible. The large torque causes the armature to begin to spin with the maximum amount of power and the armature starts to rotate.

Series motors are a common choice for competition drag applications, presumably because of their relative light weight compared to induction AC motors, and their huge starting torque. Digital calipers are nice — non conductive plastic ones are a smart move. Forney Lug Crimping Tool. Central Hydraulics 12 Ton Shop Press. Making connections…. Congratz on the good post. I read that the differnce arrises from the back-emf in the windings, but i dont understand how this difference arrises since their construction is so simmilar.

Seller information evdrives Contact seller.Electric motors have been vastly improved in recent years, especially for applications that require high efficiency and torque at a wide range of speeds - such as your EA sailboat.

To do this, the motor controller receives its instructions both from the throttle control, and from sensors in the motor itself, which signal its needs of the instant. The process is entirely reversible, so moving between forward and reverse is purely electronic and requires no gears.

With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor's internals can be entirely enclosed and protected from dirt or other foreign matter. The motor used in the EA system takes full advantage of this by being totally enclosed, a big plus in the marine environment.

This motor was designed especially for marine propulsion by John Fiorenza, an icon in the field, and is beautifully manufactured to his exacting specifications.

You can learn more about this motor model ME at his website: www.An ex-NASA engineer named Neal Saiki started a company in called Electricross, and his first product was an electric dirt bike, which I think was a great decision.

When they went into production, they immediately provided an optional pack made from lithium-Ion cells, which has a more stable voltage throughout its full-to-empty range and also provided more miles of riding.

The entire dirt bike weighed roughly lbs, and the rolling chassis with no battery was lbs. The name change was needed because they decided that…the overflowing response from customers, magazines, and potential investors had persuaded them that they needed to also make a street version, and they wanted a new name that was less motocross-specific. By using a brushed motor, the controller could be fairly simple and affordable. Here is a video of adjusting the timing of the brushes, which also shows the internal configuration.

Here is a video from Jozztek which shows the disassembly and internal configuration of the Agni-R The R stands for reinforced, so that it can withstand higher RPMs. From the beginning up until the major changes in the model year, Zero used axial-flux motors. An axial-flux is like plates that are spinning side-by-side, rather than a radial configuration, which is more like a cup spinning inside another cup.

In the pic above, an Agni-R is in a vice on its side. With the Agni motors, the permanent magnets that are on the insides of the side-plates are stationary, and the central brushed armature spins. The brushed controller for the Zeros is the Alltrax AXE, and the name indicates that this model has a nominal rating of 48V it will accept voltages up to 60Vand can provide temporary peaks of up to amps.

The controller was later upgraded to the AXE The 44V battery packs that Zero used were reasonable in view of the batteries that were available at that time. However, they do not compare to the exceptional performance of the modern versions.

The battery is another story. Once it is too worn to continue using, Zero does not make any new legacy battery packs replace them. There is some good news though…you might be able to replace a worn Zero battery with salvaged Nissan Leaf cells see pic below. Thoroughly research this before attempting it. Sooner or later, all EVs like the Nissan Leaf will have a few examples become involved in a wreck.

If the battery pack is in good shape and has only a few miles on it…there has definitely been a market developing for lithium cells of all types. The model year saw some big changes, and they were significant improvements. The cells were flat pouch cells made by EIG Energy Innovations Group from South Korea and were configured as an 18S pack, which had a nominal voltage of roughly 65V this is the only year that this voltage was used.

From this point forward, Zero has used flat pouch cells. However, there is a warranty recall in-place for the packs, concerning some of the insulation wearing away from vibration. If you have one of these, please contact your closest Zero dealer to have this fixed. This was also the year for big changes in the motor. Customers wanted more power, and the Agni was only an efficient HP scooter-motor. The Agni axial-flux brushed motor, shown here in a Zero DS.

The brushes are on the left side, and the flex-hose is blowing air onto them to clear dust from brush-wear and then through the motor case for cooling the armature.Well, this little trinket is going to show the same voltage V and the same horsepower ratings 41Hp — Hp at 20lbs less 35lbs vs 55lbs.
