The accepted terminology is either neurotransmitter or neuromodulator. The compounds are epinephrine, ACh, norepiniphrine, GABA, glycine, ATP , ADP, adenosine, glutamate, aspartate, substance P, Neuropeptide Y, LHRH and probably 2 dozen others. In addition NO (nitric oxide) acts as a neuronal released modulator (albeit not by synaptic release).

Acetylcholine
The synaptic knob contains vesicles filled with neurotransmitters. Therefore, Acetylcholine is the neurotransmitter that stimulates skeletal muscle to contract. It is released into the synaptic clefts between motor neuron axons and motor end plates.

axion terminals
Normally there are six terminals (two terminals per winding in 3 phase system) for a motor. If you find 12 terminals, you need to read the motor name details or specifications to get more info. The motor could be with two different sets of winding (double speed motor)
short the rotor terminals.
