Motor torque calculator12/28/2023 ![]() Theoretically, inertia is factor of mass so it should not include gravity, however, practically we can not easily measure mass on the earth. The former includes gravity, the latter only mass. The units of inertia are commonly used in two ways, oz-in² and oz-in-sec². Moment of Inertia Calculation for an Object in Linear Motion Moment of Inertia Calculation for a Rectangular Pillar Moment of Inertia Calculation for an Off-Center Axis Moment of Inertia Calculation for a Hollow Cylinder ![]() Moment of Inertia Calculation for a Cylinder Moment of Inertia Calculation for a Rotating Object When you try to make it move that mean you want to change the speed of the object from 0 to any, there will be moment of inertia effect. When an object is just sitting without any motion, the moment of inertia is 0. Moment of inertia is the measure of an object's resistance to changes in its rotation rate. There are three factors to calculate when sizing a motor Moment of Inertia, Torque, and Speed. Oriental Motor offers a wide range of stepper motors, servo motors, AC motors and brushless motors to meet the specific needs of your equipment.įinally, after selecting the motor type you'll make a final determination of the motor by confirming the specifications of the selected motor (and gearhead if applicable) satisfy all of the requirements, such as mechanical strength, acceleration time and acceleration torque. Once you've calculated the inertia, torque and speed for the motor you'll select the type of motor based on the required specifications. (Refer to the below sections on calculations for each.) In order to determine the performance you'll need from the motor, there are three factors to calculate Moment of Inertia, Torque and Speed. Specific features and requirements such as Open-Loop, Closed-Loop, Programmable, Feedback, IP rating, Agent approvals, etc.Positioning distance and positioning time.Next you will need to determine the required specifications for the equipment: Friction coefficient of the sliding surface of each moving part.Dimensions and mass (or density) of each part.Dimensions and mass (or density) of load.that are required for the load calculation: Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. The first step is to determine the drive mechanism for your equipment. Our Technical Support Staff is available to assist you in properly sizing and selecting your motor based on your individual application. ![]() In addition to the information below for properly sizing a motor, Oriental Motor offers online motor sizing tools as well as assistance from our Technical Support staff. Proper sizing and selection of a motor for your equipment is key to ensuring performance, reliability and cost of the equipment. ![]()
