Stepper motor ampage question

[m_c]

It depends what you mean by hybrid. Pretty much all stepper motors you buy now are technically hybrid motors (most square motors are hybrid), and they are far better than conventional (typically round) stepper motors.

A quick search of eBay has thrown up the likes of this - https://www.ebay.co.uk/itm/200W-220V...e/253850778051
And they also sell a 500W version with a basic speed controller - https://www.ebay.co.uk/itm/500W-220V...d/253982275690

To give you some reference figures, using the speed torque curve of a leadshine nema 23 motor (http://leadshine.com/productdetail.a...S&model=57HS22 - one of the first motors I found that has the needed data), at 2000RPM depending on configuration/supply voltage it's only producing 0.4 to 0.7Nm, which works out at 80 to 150W of mechanical power. To get that relies on driving the motor at 68VDC. Drop the voltage, and the torque will drop of far quicker.

At that point costs are verging in to the same as buying a small single phase motor, or even three phase and cheap VFD. A quick ebay search shows a 1/2HP 3 phase motor can be had for £62, and a suitable VFD for £45. It will likely cost you more than that to get a suitable 68VDC power supply and suitable stepper drive.
The only thing with using a standard induction motor, is they are far larger than a similar power DC motor.
