- the static
**friction torque**course is shown. From the Figure 5 is obvious that**friction torque**decrease when DC**motor**output shaft starts rotate. From performed measurements it can be state a DC**motor friction**course which is on Figure 6 shown. Figure 4.**Friction torque**course for constant angular velocity . - To establish the
**torque**equation, let us first consider the basic circuit diagram of a DC**motor**, and its voltage equation. Referring to the diagram beside, we can see, that if E is the supply voltage, E b is the back emf produced and I a, R a are the armature current and armature resistance respectively then the voltage equation is given by,. But keeping in mind that our purpose is to derive ... - Mach III
**friction torque**limiters, also known as slip clutches, are designed to transmit a fixed amount of**torque**from one machine component to another until an overload is experienced. A**torque**setting is established by compressing the adjustment nut to the desired**torque**output, then fixing it in place with the provided set screw (s). - The dissipative
**torque**corresponds to the energy that is converted into heat. In practice the dissipative**torque**is a very non-linear function of speed and bearing temperature. In the case where the load has separate bearings and is not aligned perfectly with the**motor**, the lost**torque**can also be a function of the shaft-angle. - This can be calculated by multiplying force ( F) by the rotation radius ( r ). In order to move the load (blue box), the
**motor**must generate more**torque**than this value. To calculate load**torque**, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 ...
