Then, mt / ft is the encoder period, and ft / mt is the number of encoder pulses per second. Therefore, the shaft speed, Nf in rpm is calculated as 60f t N f = Pprmt (rpm). The Tmethod is more accurate in a lowspeed region, but becomes less accurate as the speed increases, mt being small. Thus, it is not appropriate for highspeed measurements. Fig. 10.25 compares the measurement errors of the Mmethod and. 288 AC Motor Control and Electric Vehicle Applications.Generally speaking, as the gear ratio is high for the transmission system, motor control precision has very small impact to the tracking precision. For example, for a system with the gear ratio of 20000:1, the tracker only covers an angle of 0.314mrad when a one complete circle is

finished.by the motor. Therefore, all kinds of the motor can satisfy the precision of the tracking system. However the feature of each type of motor is different.

Speed control of an AC motor is possible using a variable frequency drive (VFD). Speed regulation is as good as the speed feedback allows—better than 1% regulation is common when using a highquality tachometer or an encoder.Ratemeter/DVM and cam/a.c. motor arrangement. b.

some.of the tests. The motor speed is adjustable, and three different wheelchair angular velocities (3.0, 3.8, and 4.8 rad/s) are used for the dynamic tests (Figure 4.4). The equivalent linear velocities are 3.15, 3.98, and 5.03 increases the value of the output by 360 per each revolution of the shaft of the encoder. A single PC is not used for both measurements FIGURE 4.3 There are a number of disadvantages of the vector controlled AC drive, when compared to a DC drive: • The vector controller is far more complex and expensive when compared to the simple cascade controller of a DC drive. • Encoder speed feedback is usually necessary to obtain accurate feedback of the motor shaft speed. Fitting these encoders to a standard

squirrel.cage AC induction motor is often difficult and makes the motor more expensive. In recent years, 'Sensorless' vector The brushless dc motor control has an "electronic commutator" fed by an integral encoder mounted on the motor. This encoder tells the motor control which transistors should be turned on to obtain maximum torque from the motor at whatever position the motor shaft happens to be in at that point in time. Encoder data establish a communication between the motor and its control that is not present in ac motors and inverters, and that is not a part of the dc brushtype motor and its SCR  AC motor actuator drives, and to count the revolutions of the azimuth and elevation drive motors during solar

tracking.operation. Most industrial motors simplify this challenge as motors often include (check this when you purchase a solar tracker motor) an integrated magnetic pulse generator for the output of magnetic pulses to a magnetic pulse encoder. To convert the motor rotation pulse counts into solar tracking angles, your microprocessor simply have to do a quick computation.
