Is Slotless Motor Slower Than Shinkansen Motor?

[changkh]

Have been inactive for some time.

 

Due to Doctor Yellow being retired in Japan, am thinking of purchasing one and it happens that Kato will re-releasing in June. I noticed something new mentioned in the poster - slotless motor installed.

 

As I have no idea what this was, I tried to find some videos about this motor. One particular video which I embedded, mentioned that this motor is meant for normal trains and if replaced on a shinkasen train, the speed will be slower.

 

Since this is a 3 year old video, not sure if it's still valid anymore. My current trains are already running slower after changing to the latest power packs so if this motor makes it slower, I might get one of the older models without slotless motor instead.

I had not heard the term "slotless motor" before so I looked it up.  It refers to how the windings are done and is supposed to provide smoother and quieter operation.  Don't know if it will be any different speed than previous motors used on Kato products.
