Motor Power Calculator
Read full descriptionHide full description
The Motor Power Calculator application calculates the motor power by inputting the motor speed and the force generated by the motor. The power of the motor is calculated in seven units such as watt [W] and horsepower [PS], [HP]. Switch the two modes of the rotational motor and the linear motor at the top of the application screen. In ""ROTATIONAL MOTOR"" mode, input rotational speed and torque, and ""LINEAR MOTOR"" mode input speed and thrust(force).Units supported by this application are as follows. [Power] 7 kinds of [W], [PS], [HP], [kgf · m/s], [kcal/h], [Btu/h], [ft · lbf/s] - Rotational motor - [Rotational speed] 4 kinds of [rpm], [rps], [deg/s], [rad/s] [Torque] 9 kinds of [N · m], [cN · m], [mN · m], [kgf · m], [kgf · cm], [gf · cm], [lbf · ft], [lbf · in], [ozf · in] - Linear motor - [Speed] 2 types of [m/s] and [mm/s] [Thrust] 8 kinds of [N], [kN], [dyn], [kgf], [gf], [tf], [lbf], [pdl]
