The split phase motor may not enjoy the constant stalled condition.
The DC motor shouldn't care.

Primarily, it would not enjoy it because they're (gear motors) usually
fan cooled, and the fan wouldn't be running during stall.

But I forgot something important, anyway. Split phase motors don't mind
being stalled OR operating at reduced voltages, but they don't develop
much starting torque below a certain saturation voltage. Only a "bang-
bang" control would work with a typical split-phase type motor.

A DC motor would be perfect -- don't have one that fits my gear reducer,
but I can get one. A 3-phase motor would be OK too, with the dancer
driving the frequency pot of a VFC.
