The combined inertia of the motor rotor and the load reflected on the motor shaft.

The inertia of the load reflected on the motor shaft.

The inertia of the motor rotor.

The ratio between the motor rotor inertia and the reflected load inertia.

The torque generated by the motor.

The resistive torques acting on the system, including friction, gravity, and external forces.

The total torque acting on the system, calculated as the difference between the motor torque and the resistive load torque.

The relationship between the total inertia, angular acceleration, and total torque of the system.

The ratio between the speed of the load and the speed of the actuator.

The torque required to move the load and overcome friction in the transmission.

The desired movement profile of the load over time, often described as angular displacement (θ) vs. time (t).

Calculating the required torque history for the actuator based on the desired motion profile, reflected load parameters, and actuator inertia.

The maximum torque required by the actuator throughout the motion cycle.

A measure of the average torque required by the actuator over the entire motion cycle.

Verifying that the selected actuator meets performance requirements based on peak and RMS torque, and maximum speed capacity.

A type of actuator that provides precise control over angular or linear position, velocity, and acceleration. It typically consists of a motor coupled with a sensor for position feedback.

The study of how objects move in a straight line. It is governed by Newton's second law of motion: F = ma, where F is the force, m is the mass, and a is the acceleration.

The study of how objects rotate around a fixed axis. It is governed by Newton's second law of motion for rotation: T = Jθ, where T is the torque, J is the moment of inertia, and θ is the angular acceleration.

The time required to move an object through a certain distance under a constant force is given by the equation t = 2ms/F, where t is the time, m is the mass, s is the distance, and F is the force.

The time required to rotate an object through a certain angle under a constant torque is given by the equation t = 2Jθ/T, where t is the time, J is the moment of inertia, θ is the angular displacement, and T is the torque.

It is the mass of an object distributed around its axis of rotation. It represents how difficult it is to change the rotational speed of an object.

It refers to the portion of the motion cycle where the system is at rest or holding a constant position.

The process of determining the size and specifications of an actuator, like a motor, to meet the requirements of a system.

The time it takes for the actuator to reach its maximum speed.

The time the actuator maintains a constant speed.

The time it takes for the actuator to slow down from its maximum speed to a stop.
