WebbAt an elevated motor temperature, the slope of the DC motor curve increases as a result of an increase in no-load speed and a decrease in locked rotor torque (sometimes referred to as stall torque). WebbThe stall current of a DC motor is how much current the motor will draw when power is applied but it is not spinning (for example, if the motor shaft is prevented from rotating), …

Stall torque is the torque produced by a mechanical device whose output rotational speed is zero. It may also mean the torque load that causes the output rotational speed of a device to become zero, i.e., to cause stalling. Electric motors, steam engines and hydrodynamic transmissions are all capable of … Visa mer Electric motors continue to provide torque when stalled. However, electric motors left in a stalled condition are prone to overheating and possible damage since the current flowing is maximum under these conditions. Visa mer A hydrodynamic torque multiplier (torque converter) produces stall torque when the load prevents the turbine (output stage) from rotating while … Visa mer In the case of a petrol (gasoline) or Diesel engine, the stall torque may refer to the torque load that causes the engine to stall. The actual amount of … Visa mer WebbThe torque constant is a design parameter, including geometry and the magnetic field density and the winding. The physics behind is that of the force felt by a current-carrying wire in an external magnetic field (Lorentz force). Torque and current are strictly proportional for coreless maxon motors. The two are equivalent for a given motor.
