sin²-shaped motion profiles
In the case of the sin
2
-shaped motion profile, acceleration is effected in a sinusoidal manner. The
jerk is also sinusoidal, i. e. continuously. The maximum values of torque and speed are not reached
simultaneously; like this, the motor can be better utilised at higher speeds.
• The maximum speed that can be reached is higher than in the cases of the linear and S-shaped
motion profiles.
• In comparison to the S-shaped motion profile, the Base process power is greater.
• Since the acceleration is effected in a sinusoidal manner, the maximum acceleration is greater
than in the case of the linear motion profile (57 % of the acceleration of the linear motion pro-
file).
• sin 2 -shaped motion profiles in the torque-speed diagram of the motor are represented in a cir-
cle of ellipsoidal manner.
