Straight instead of angled stator slots, 52 coils without the copper wasteful overlapping windings, lots of magnets, and dual stamped steel plates riveted together to form the spoke portion of the stator...a wholesale change in the motor design. Maybe Clyte is about to capitalize on its name with some new mass produced motors out of another factory and stamping Crystalyte on the covers. If so, I hope the price comes way down.
It is absolutely crystalyte stator, got them directly from crystalyte.
The Hx series is the newest crystalyte product line in 2011. It is really a mix of 9c, xlyte 4x, 5x, Bionx all in one.
The similarity to 9c is stamped steel plate. It reduce the weight of the motor instead of using cast stator, it is also cheaper to produce. As result, we will see crystalyte motor price drop $50 - $80 less the current pricing (each dealers may price differently).
408 motor weight 16 lbs (7.25kg) , and 5304 weight 24 lbs (10.86kg)
Hx front motor weight 12 lbs (5.4kg)
Hx rear motor weight 16 lbs (7.25kg)
Instead of using curved magnet in the motor case, it has been changed to smaller and straight magnet. This also help to reduce production cost.
The similarity to Bionx is the exterior motor case. The disc mount is very close design to Bionx motor case. The Bionx had the narrowest flange distance 35mm, Crystalyte Hx had 38mm. Which doesnÃ¢â‚¬â„¢t require any dishing to the wheel.
By increasing the dimension of the stator, it will provide more power.
408 stator dimension is about 171mm
5304 stator dimension is 204mm
Bionx stator is about 190mm
Hx stator is 198.4mm
What really surprise to me is that Crystalyte came out with the sensorless controller and motor combination. I am a big fan of senorless controller, I have been asking Crystlayte to make sensorless controller for many years. They finally make one this year. However, during my early testing, if I have to run at 72v 40 - 50amp controller, I still wanted my senored controller and motor combination.
