  • What is Commutation? Motion Control OnlineTo understand the process of commutation a circlegraph can help explain. The current which flows through a coil unit has the shape of a sinus. The Ycomponent of an arrow in the below circlegraph determines the magnitude of that current. As the arrow makes a full rotation the magnitude follows a sinus pattern. The currents are 120?degrees out of phase, demonstrated by the three arrows being equally spaced over 360 degrees.

    There are a couple of ways to determine the position of (electromagnetic) coils over the magnettrack (or rotor). If the detail and precision of an encoder (ruler) are not needed, an analog hallsensor can be used to measure the position of the coil unit. Digital hallsensors are used to commutate the current. Advantages and Risks An easy way to align the current though the coils with the permanent magnets is by using a hallsensor. Hallsensors can be analog or digital. Analog hallsensors measure the exact magnet field. The signal will be stronger when centered over a magnet pole. The magnetfield equals zero when measured between two opposite poles. Digital hallsensors only measure a positive (North) or negative (South) magnet pole. They show a digital readout, meaning a 1 or 0. When a digital hallsensor is over a pole of their type (north or south) they give off a signal. The process of commutation in a synchronous motor is that of switching between the phases. It is pos

    To summarize what is needed to effectively move a linear or torque motor: commutation of the current phases and optionally a Hall effect sensor. The 3 phases of current need to be controlled continuously in order to generate motion. Hall sensors can be used to determine the position of the forcer within the magnetic field for a controller to correctly commutate the phases. Digital hallsensors use 3 signals, also spaced at 120 degrees over their specific magnet pitch. Tecnotion digital hall sensors require a supply voltage between 4,5 V and 28 V dc. The analog hall requires a 5V power supply.

  • Methods of Improving Commutation Resistance &Voltage The Resistance Commutation method uses Carbon brushes for improving commutation. The use of Carbon brushes makes the contact resistance between commutator segments and brushes high. This high contact resistance has the tendency to force the current in the shortcircuited coil to change according to the commutation requirements.

    In the Voltage Commutation method, the arrangement is made to induce a voltage in the coil undergoing the commutation process, which will neutralize the reactance voltage. This injected voltage is in opposition to the reactance voltage. If the value of the injected voltage is made equal to the reactance voltage, there will be a quick reversal of current in the shortcircuited coil and as a result, there will be sparkles Commutation. The two methods used to produce the injected voltage in opposition to the reactance voltage are as follows.

    The most efficient method of eliminating the problem of armature reaction and flashover by balancing the armature mmf is the compensating windings. The windings are placed in the slots provided in pole faces parallel to the rotor conductors. These windings are connected in series with the armature windings. The direction of currents in the compensating winding must be opposite to that in the armature winding just below the pole faces. Thus, compensating winding produces mmf that is equal and opposite to the armature MMF. The compensating winding demagnetizes or neutralizes the armature flux produced by the armature conductors. The flux per pole is then undisturbed by the armature flux regardless of the load conditions. The major drawback with the compensating windings is that they are very costly. The primary use of the compensating winding is in particular cases, as given below 1. In large machine subject to heavy overloads or plugging. 2. In small motors subject to sudden reversal
