The table shows typical output values of actuators.
*1: Typical characteristics when combined (driven by ideal sine wave) with our drivers.
*2: Value after temperature rise and saturation when the 320 x 320 x 16 [mm] aluminum radiation plate is installed.
*3: Value of phase induced voltage constant multiplied by 3.
*4: For testing conditions, refer to [1-12 Shock resistance] (P51) and [1-13 Vibration resistance ] (P52).
