Synchronous Motors Ver. 0002 SM - 5
Mo, Io: Stall torque, with Io current permitted without time limit
Mp, Imax: Peak torque and maximum current
Very important: Imax must never be exceeded, because it would demagnetize the rotor.
nN: Rated (nominal) turning speed.
Pow: Rated Power = Mo •

N
/ 9550
KT: Torque constant. Torque generated depending on the supplied current.
tac: Acceleration time of the motor from 0 rpm up to its rated speed at its maximum torque.
L, R: Winding inductance and resistance between phases.
J: Rotor inertia.
P: Weight.

Motors with a power "base" which need to be connected via MC 46 type socket. All the others with MC 23.
In bold, the combinations where the drive automatically limits its peak current to avoid damaging the motor.
