sin²-shaped motion profiles

In the case of the sin

-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

-shaped motion profiles in the torque-speed diagram of the motor are represented in a cir-

cle of ellipsoidal manner.
