3.6 AC Induction Motor with Speed Tachogenerator
In the application a general purpose 4-pole AC induction motor is used.
The 16-pole speed tachogenerator is coupled to the motor shaft. Output
of the tachogenerator is the AC sinewave signal corresponding to the
motor speed. It allows speed sensing of the motor required by the control
algorithm. Detailed specifications are listed in
Table 3-4
In a target
application a customer specific motor will be used.
3.7 Sensors
The control algorithm requires speed and DC-Bus voltage sensing and
DC-Bus over-current detection. Therefore, these sensors are built on the
power stage board. Detailed schematics of the sensor circuits can be
found in the user’s manuals belonging to each board.
3.7.1 Speed Sensor
A 16-pole AC tachogenerator senses the actual speed of the motor. The
output of the tachogenerator is an AC sinewave signal, its frequency
corresponds to the motor speed. For a motor speed of 3000 rpm (100Hz
synchronous) the tachogenerator output frequency is 400Hz (4-pole
motor : 16-pole tachogenerator). The sinusoidal signal of the
tachogenerator is filtered and transformed to a logic level square wave
