Torque. times . Speed = Power. Except for friction losses, power remains a constant in a gear train. In our example above, speed was 15 times smaller on the output shaft, which means torque was 15 times greater! Our robot kit’s electric motors have high speed and low torque.

The equation for torque for an electric motor is given by: T = torque of the motor (lbf*inch.) or (N*m) r = radius of the motor shaft, pulley or whatever is attached to the motor shaft [inches (inch.) or centimeters (cm)].

where f is the output frequency of an AC drive, fnom is the nominal supply frequency (50 Hz), T is the actual torque of the motor, and Tnom is the nominal torque of the motor. The coefficients 0.2, 0.15, and 0.65 are empirical weighting factors for the different loss types.

Therefore, torque can be talked about reference to it’s formula t = f * l (torque equals force times lever arm length {radius of gear}). It can also be looked at reference gear ratio too. Example: if a motor can lift 10 lbs, and it is geared to a second shaft that has a 2:1 ratio, it can by using this setup lift 20 lbs.

Episode 415-2: Torque from a motor. An electric motor will spin up to an equilibrium speed. At that speed the electrical input power is equal to the mechanical output power plus thermal losses. If the motor is ideal it will spin with a very small current, i.e. almost zero input power and almost no output power.

[DOC File]The Tradeoffs between Engine Power and Torque
https://info.5y1.org/motor-power-formula-torque_1_c07821.html
The torque and horsepower curves for a typical small dc motor differ a bit from the internal combustion engine. The torque curve is very linear with maximum torque developed at zero rotational speed, and the horsepower curve peaks near the middle of the range. The following MATLAB plot for the small VEX dc motor illustrates these characteristics.

It is not so easy to calculate the torque at which the motor will deliver power at maximum efficiency. But there is an . algorithm. for it. An algorithm is a procedure to follow. Steps 11, 15, and 16 walked you through the algorithm for calculating the efficiency for a given torque.
