The power required in this case
P
F
is calculated as follows:
Power needed to accelerate and decelerate an asynchronous spindle
motor
There are three methods to control the acceleration and deceleration pro-
cess of the machine spindle:
Acceleration limited by time.
Different acceleration ramps depending on the speed reached.
F. H5/7
Frictional load. Required power.
µ
Friction coefficiente
Mechanical efficiency
m
L
Table mass in kg
V
Linear speed in m/min
F. H5/8
Acceleration limited by time.
T. H5/2
Acceleration limited by time.
Method
Acceleration limited by time.
Control
Speed increases linearly in time until the command
speed is reached.
Comment
The acceleration torque is constant.
F. H5/9
Different accelerations depending on speed.
