3.4.2 Data Sheet
The data sheet gives the values of motor parameters relating to the
performance.
The values of parameters are those under the following conditions.
• The ambient temperature for the motor is 20°C.
• The error is ±10%.
• The drive current of the motor is pure sine wave.
The following parameters are given on the data sheet:

Maximum motor torque
More specifically, torque with which the motor can intermittently be
operated within the current restricted range (from 0 min
-1
to the
beginning of dropping of the shoulder)
The maximum torque value is generally the product of the torque
constant of each motor and the current limit of the amplifier. This
value varies according to fluctuations in the power supply, motor
parameters, and limits of the amplifier. For some models, when the
maximum current flows through the motor, the maximum torque may
be lower than the calculated value due to magnetic saturation and
other factors.
