PROS -
Quiet
High Torque
Designed for continuous use
Electrical connection is relatively easy to get to. Will accept slightly modified push on crimp connectors
This motor had enough torque to spin the 8oz test weight at high rpm without strain.
It is easy to adapt an arm to the shaft arrangement.
CONS -
Shipping for a single unit is relatively expensive.
Motor can not easily be removed from the mounting plate. The gear train mounting is integral to the mounting plate. Pull the plate and all the gears fall on the floor.
Modifications -
I cut away the wire for the parking connection. So the parking function is undocumented. The output shaft has a splined tapered shaft and comes with a mounting nut. It was easy to drill a hole in the crank arm that was slightly undersized and use the nut to draw the arm onto the shaft. The connection was easy and secure.
Comments - This motor waves the crank arm back and forth. If you have need for this type of motion this motor would be a good choice. You'll need a PWM controller or need to run the motor at a lower voltage to keep the speed of motion down.
Unverified rumor has it that for larger orders you can contact them directly and they will work with you on the shipping cost.
