need help selecting a motor and drive
(OP)
I have a product with a manual wheel for height adjustment. My customer wants this to be motorized.
My existing product has a wheel to adjust my load.
The current speed is manual ~ 60rpm.
The torque is 1.6Nm (see attached).
The motorized speed should be about 60 – 600 rpm (this is flexible).
The acceleration is not critical.
The load must travel in both directions.
The total number of revolutions in one direction is 90. (~18”).
The max step size is 0.35% or 0.3125 revolutions (.0625”).
Can I use a motor direct or do I need a gear assembly?
Should I use DC or Servo?
Do the drive come with RS232 interface?
Thanks!
Derek

If this is just for ergonomics like an adjustable height sewing table I would keep the rpm at 60 and use a little Brother gear motor.

If this has feedback but is not high speed I would use a little Animatics servo with gearhead. These are nice little inexpensive packages with the controls on the motor and an RS232 interface. If you need to do a lot of communicating they are limited.

Jameco has a bunch but they show the torgue but not the speed. They don't show speed for steppers (only torque). How do I select a motor?
Jameco has a drive but requires a external heatsink. I would hoping to find a turn key solution. Ideally the drive would have a step up/down and move up/down AND a RS232.

These people have good selection in the size range you are looking at, inexpensive too.
