- The higher the voltage - the more torque a motor will have [1]:
- Ramifications of voltage - one can get higher performance by running at higher voltage. Higher voltage means less current for the same power - so it appears motors run cooler at higher voltage for the same performance.
- The higher the current - the more torque (T): Torque is proportional to current[2].
- Why does a motor have less torque at higher speed? The motor acts as a generator, producing back EMF, reducing the applied voltage. A motor in motion must also overcome inductance of the windings.
