Issue with 1.5HP motor on 20L Glass Reactor - are missing a component to drive?

Hello!
We currently have this M12 electrical connection for the motor. We had switched that connector to a standard 110VAC plug and plugged it into the wall outlet. When we plugged it in the motor did not turn over and spin the mixer. We then gave the mixer a little push and it started to spin counter clockwise. We then unplugged the motor and stopped the mixer from spinning. Once we plugged it back in, the motor did the same thing where it wasn’t spinning. We then gave it a push in the clockwise direction and it started to spin in that clockwise direction.

Has anyone had an issue like this to get the 1 phase 110VAC motor running properly? Is there a special signal that the M12 connector would normally provide to bump the motor into one direction or the other that the standard 110VAC wall plug would not give? The motor seems to be fine as once we gave it a direction to spin the motor would take over and keep the mixer running in the direction we bumped it. Any insight to this would be greatly appreciated.

check the start cap first.

edit: don’t get zapped, capacitors can carry a charge… think taser…

correction! Not sure why I wrote 1.5HP motor… it’s a probably more like .5 HP.
anyway. 1.25 amp, 90W

you’re missing a piece…

the unit is much less useful without speed control on the agitator.
that M12 plugs into the speed control box.

don’t know where you got yours, but you could RTFM courtesy of USALAB: USALAB reactor manual which is where I stole the above image.

note: your thermometer probably plugs in there too…

As If By Magic… thanks.!
We thought we were missing some sort of VFD/Control unit.
Will look into sourcing.
