WebThe series DC motor produces very high starting torque and, as previously mentioned, will run away at no load. As an example, series motors are useful for driving subway cars where high torque at standstill is required. 400% torque can be provided with only 200% current because of the squared relationship. WebThe DC Motor block uses manufacturer datasheet parameters, which specify the motor as delivering 10W mechanical power at 2500 rpm and no-load speed as 4000 rpm when run from a 12V DC supply. Hence if the PWM reference voltage is set to its maximum value of +5V, then the motor should run at 4000 rpm.
