SELECTING CRITERIA
5.1
Synchronous motor selection
5.1.1
First motor pre-selection
The motor selection will depend on the mechanical and dynamic response
characteristics that it must satisfy. Hence, the motor must meet the
specifications on torque (N·m), speed, duty cycles or other kind of
requirements 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
considered in many of the following calculations:
The continuous torque
