Dear All I like to know about the relationship between current, voltage, speed, Torque, coil length of motor, coil diameter and if any of the above changes how other parameters get affected. Thanks Satheesh

The maximum torque occurs at 0 rpm, and is called stall torque. The minimum torque (zero) occurs at maximum rpm, reached when the motor is not under a load, and is thus called free rpm. The formula for torque at any given rpm is: T = Ts - (N Ts ÷ Nf) where T is the torque at the given rpm N, T s is the stall torque, and N f is the free rpm.
