# Calculate stall torque dc motor

May 03, 2017 · DC motors are pretty much linear, the faster they turn, the less torque they have. Max torque occurs at stall (as does maximum current) Drawing the torque-speed curve can be done by measuring the...

The torque of a motor is the amount of force that an engine generates. This force is used to rotate a lever arm attached to the engine, which in turn propels the entire vehicle. Torque determines the towing force of a vehicle as well as its rate of acceleration.

Mar 09, 2017 · The Torque Equation and the Relationship with DC Motors March 9, 2017 By Danielle Collins Leave a Comment Understanding the torque equation and the relationship between speed and torque is an important part of selecting and operating a DC motor. In general for small electric motors (and the kit motor is not an exception) maximum power is at approximately 50% of stall torque where the speed usually is at 50% of maximum no-load speed. Maximum efficiency is usually at 10-30% of motor stall torque, or at 70-90% of no-load speed. At each point selected for calculation, the efficiency of the motor is the mechanical power output divided by the electrical power input. Once again, a sample table for motor M2232U12G is shown in Table 1. and a sample curve in Graph 1. Maximum efficiency occurs at about 10% of the motor stall torque. Apr 25, 2014 · How to calculate torque of a dc motor. I have got a dc motor with imprint: maxon motor 314888 swiss made 1130329<> I can vary its speed, direction & control barke with a drive along with it, but don't know exactly how to calculate torque.

Sep 26, 2019 · The torque equation of DC motor designs is torque = IBA_sin_θ for each turn of the motor with the electric current I in amps, magnetic field B in teslas, area outlined by the coil A in m 2 and angle perpendicular to the coil wire "theta" θ. To use the calculate torque of DC motor designs, make sure you understand how the underlying physics works. To get an accurate value, you'll have to measure it. Find someone who has a "bench dyno" and make friends with them :-) You can estimate if you know the efficiency of the motor. 2200 Watts is about 3 Horsepower, and torque is horsepower divided by rpm times 5252 (yes, that's an arbitrarily chosen constant everybody uses!) In general for small electric motors (and the kit motor is not an exception) maximum power is at approximately 50% of stall torque where the speed usually is at 50% of maximum no-load speed. Maximum efficiency is usually at 10-30% of motor stall torque, or at 70-90% of no-load speed. The stall current is inversaly proportional to wiring resistivity and the rotor generates a counter emf proportional to rpms, if I read them correctly under No LOAD condition draws 0.52 amps and turns at 15800 rpms while during full charge draws 2...
