Stall Torque Calculator

Formula

The formula to calculate the Stall Torque is:

\[ T_{stall} = I_s \times K \]

Where:

\(T_{stall}\) is the Stall Torque (N-m)
\(I_s\) is the stall current (amps)
\(K\) is the motor's torque constant (N-m/amp)

What is Stall Torque?

Stall torque refers to the maximum torque that a motor can generate when it is not rotating (i.e., at stall). It is an important parameter in motor design and performance evaluation, as it indicates the motor's ability to overcome initial resistance and start moving.

Example Calculations

Example 1:

Stall Current (Is) = 10 amps
Torque Constant (K) = 0.5 N-m/amp

Using the formula:

\[ T_{stall} = 10 \times 0.5 = 5 \, \text{N-m} \]

The Stall Torque (Tstall) is 5 N-m.

Example 2:

Stall Current (Is) = 15 amps
Torque Constant (K) = 0.8 N-m/amp

Using the formula:

\[ T_{stall} = 15 \times 0.8 = 12 \, \text{N-m} \]

The Stall Torque (Tstall) is 12 N-m.
