SELECTING CRITERIA
5.1 Selection of the synchronous motor and its associated drive
First motor pre-selection
The motor selection will depend on the mechanical and dynamic re-
sponse characteristics that it must satisfy. Hence, the motor must meet
the specifications on torque (Nm), speed, duty cycles or other kind of re-
quirements of the motor to be moved.
Calculation of the necessary motor torque (M)
The required total motor torque
M
T
has two components:
•
The static torque
M
S
to maintain the table at a constant speed or fixed
in a position.
•
The acceleration torque
M
A
to change its speed.
The reduction in the motor ballscrew transmission [
i
] is a factor to be con-
sidered in many of the following calculations:
