Tomy doesn't make a two speed motor. The motor numbers are refering to the motor's revolutions per minute... RPM. The only two speed motor that has ever been advertised as a being made for two speeds is the Perfection 4.2 Pro, but there is questions as to what perfection did to actually make it two speed...
Anyhow, there is not much consistency with these motors. Some motors take a while before they get up to speed. Other times, a motor's output will decrease quickly after use. I have heard of using motor grease and a constant higher voltage to punish a motor into working again, havn't gotten around to testing this out for myself yet.
