6 - DC Motor Animation

System in Analysis

The complete example code is available here.
The mechanical powertrain to be studied is the one described in the 5 - DC Motor PWM Control example.

Model Set Up

We can get an animation of the DC motor’s working characteristics:

from gearpy.utils import dc_motor_characteristics_animation

dc_motor_characteristics_animation(motor = motor,
                                   time = powertrain.time,
                                   interval = 10,
                                   figsize = (10, 5),
                                   torque_unit = 'mNm',
                                   current_unit = 'mA')

See dc_motor_characteristics_animation for more details.
On the left hand side there is the torque-speed characteristic, while on the right hand side there is the torque-current characteristic and the orange dot is the working point of the motor. The characteristics can vary based on the PWM value.
