We are studying the use of a permanent magnet DC motor in a roller motion application. The motor has a voltage Vk, an armature resistance Ra, and when it turns a cylindrical roller (load) at n revolutions, it draws a current ia. The torque required by the load is proportional to the angular velocity ω with a proportionality coefficient Kφ. All losses except for ohmic are negligible. ia = 19A, Vk = 230V, n = 380, Ra = 4.5.calculate the mechanical torque delivered to the load (roller),
