Best money can buy Chinese 1-Phase spindle + VFD

[rando]

Check out Jian-Ken spindles. They're not the cheapest, but I've been running one for a few years now and it's been good. I use a Sunfar VFD with it.

Thanks. Should I go with constant power (JGH-105/2.2) or constant torque (JGD-105/2.2) model?

That will depend on what you're using your machine for. For instance if you're machining wood and running at full rpm most of the time, then a constant torque spindle is probably better. If on the other hand you're working with metal and need a range of rpm to suit the optimum cutting speed with different size cutters and materials then the constant power will likely be better as you get more torque at lower rpm.
