Hi,

The drive of the Bachmann Streetcar


http://www.bachmanntrains.com/home-usa/products.php?act=viewProd&productId=423

is often used as drive unit for Gn15 locos. Does anyone know the producer of the motor in this drive? There's no advice printed on the Motor.

I have one of these somewhere. Unsure of the motor's maker but chances are it's some outfit in China.

I'm sure it is some chinese doings. If it's a replacement you're looking for, well, you live in Germany so I'm sure you could find a nice Faulhaber for a decent price.

Hi,

although I prefer coreless motors in my locos on 32mm track, I try to avoid this in this case. I run my locos with RC and battery and for Gn15 I need to use the smallest possible esc. But the esc I use has a pwm frequency of 50Hz. For a coreless motor you should have at least more than 3kHz.

So a "normal" motor would be better in this case. The built in motor is a 12V type. That works so far with 2 Lipo-cells, but a e.g. 6V type would be nicer as one cell would be suficient.

The place for the motor in this Bachmann drive is fitted especially for the built in motor. Taking one with not exactly the same geometry, will cause the need of cutting and milling. And then, it is easier for me to built it completely by myself.

But I have found another drive with same axle distance from a small austrian manufacturer. I will see if he could offer a lower Volt type as 12V.

And if not, I start my CAD and design an own drive for GN15.

Juergen
