Common Explanations of characteristics

Power consuption Pin
The power consumtion expressed in W was determined in no-load operation.

Load
The total sum of all static and dynamic torques (e.g. friction torque, mass inertia, acting on the rotor).

Speed n
rmp =  revolution per minute

Torque
The running torque in cNm (also synchronous, braking or dynamic torque) defines the load at which the synchronous motor falls out of synchronism and stalls.

Power output
The power output expressed in W is determined according to the following formula.



Md in Nm (1 cNm = 0,01 Nm), n in rpm

Pole pair number
The number of rotor pole pairs North/South.

Direction of rotation
This information always refers to the output shaft, either of the motor or of the gearbox.
Right = clockwise rotation (CW)
Left = counterclockwise rotation (CCW)

Gear torque
The maximum gear torque in cNm defines the maximum load for a required life of at least 1000 operating hours.

Running time
This value refers to the time (t) per revolution (U); they are calculated using the following formula.



i = transmition ratio
n = motor speed

Axial thrust / lateral force / lateral torque
These values refer to the loads on the standard output shaft of the respective gear.
The permissible lateral torque referring to the standard shaft must not be exceeded on special shafts either.
