Reflected load inertia is the perceived inertia of an assembly at the motor drive shaft of a rotary motor.
Reflected load mass is the perceived mass of an assembly at the motor drive shaft of a linear motor.
You can use reflected load information to help select an appropriately sized motor to withstand the load. For Motion Analysis studies, you can compute and plot reflected load results.
You cannot include reflected load results in expressions.
When external or internal forces cause an assembly to move, the calculated reflected load inertia or reflected load mass varies with time. Reflected load calculations include the effects of gravity, friction, and externally applied forces or torques.
Define reflected load inertia or mass results for constant speed motors. If you define reflected load inertia or mass results for other types of motors, such as oscillating or distance motors, the results might exhibit numerical singularities that do not represent the physics of the motion. Such numerical singularities are prominent near zero velocity or when the velocity changes from a positive value to a negative value.
