![]() ![]() Velocity Converter Convert between speed and velocity units like m/s, km/h, knots, mph and ft/s.Projectile Range Calculate the range of a projectile - a motion in two dimensions. ![]() Power Power is the rate at which work is done or energy converted.Kinetic Energy Energy possessed by an object's motion is kinetic energy.Impulse and Impulse Force Forces acting a very short time are called impulse forces.For example, an unloaded DC motor might spin at 12000 rpm and provide 0.1 kg-cm of torque. Adding a geardown both reduces the speed and increases the torque. Gear motors are essentially DC motors with an added geardown. Improvised Torque Wrench Improvise a torque wrench with a luggage scale. To get feedback of the angle or the speed of the motor, consider a motor with an encoder option.Formulas of Motion - Linear and Circular Linear and angular (rotation) acceleration, velocity, speed and distance.Flywheels - Kinetic Energy The kinetic energy stored in flywheels - the moment of inertia.Unit symbol description: W watt, KW kilowatt, lb pound, kg kilogram, cm centimeter, hp horsepower. Power and Speed Electric motor output power and torque vs. Engine motor speed torque power calculator. Electric Motors - IEC and NEMA Standard Torques IEC and NEMA torque classifications of electrical motors.Speed and Time - Calculator and Chart Velocity plotted in time used diagram. Conservation of Momentum The momentum of a body is the product of its mass and velocity - recoil calculator.Conn-Rod Mechanism The connecting rod mechanism.Dynamics Motion - velocity and acceleration, forces and torque. The Kv rating of a brushless motor is the ratio of the motors unloaded RPM to the peak (not RMS) voltage on the wires connected to the coils (the back EMF).I = moment of inertia (kg m 2, lb f ft s 2) Power and rpm chart Torque of a Body in Angular Motion The torque created by the motor (without losses) can be calculated by rearranging (1) toĭownload and print Motor - Torque vs. Note! - an object - like an electric motor - can have an active moment without rotation, but without rotation ( ω = 0) there is no power produced.Įxample - Torque created by Rotating MotorĪn electric motor runs with 3600 rpm with an measured power consumption of 2000 W. N rpm = rotations per minute (rpm, 1/min) The power of a rotating body can be expressed as Power and Torque of Body in Angular Motion Power is quantified in watts (J/s) or horse power. Power is how rapidly work is accomplished - work in a given amount of time.Since torque is a vector acting in a direction it is commonly quantified by the units Nm or pound-feet. The more torque the motor produces, the greater is its ability to perform work. Torque is a rotating force produced by a motor’s crankshaft.Output mechanical power of the motor could be calculated by using the following formula: P out. It is motor speed and torque the turning force of the motor. Work is quantified in joules (Nm) or foot-pounds. Motors supposed to do some work and two important values define how powerful the motor is. Work is the result of a force acting over some distance. ![]()
