Re: Motor setup being used in this video. Heavy Z-Axis motor setup
The motor in the video looks to be a 1.5kW to 2kW just based on the size. It is a servo motor, no idea of the brand. It also looks like it is attached to a reduction gear set of some kind.
You could use a clock motor to lift the weight if you geared it down enough, it's all a matter of how fast you want to lift. Greater acceleration requires more power.
A better choice of motors IMHO would be DMM Technologies or SureServo2 (Delta) from Automation Direct.
