DC-servo modules general informations
The Mesanor DC Controller modules are designed for four-quadrant speed control of permanent magnet DC motors. Through a corresponding power supply module (for example MSMNW) input alternating voltage will be changed into DC bus voltage. By comparsion of speed demand and effective speed (tacho voltage) the amplifier is generating the speed demand for the current controller. The current loop is controlling the output current following the current reference value. the output current is pulse width modulated. Due to high switching frequency the system has a very large bandwidth and a good dynamic
| The following relations are important for the operation of the motor: |
 The torque is
proportional to the output current |
| The speed is
proportional to the tacho voltage (armature voltage) |
| The direction of
rotation corresponds to the polarity of the tacho voltage (armature
voltage) |
AC-servo modules general informations
The Mesanor AC Amplifiers are extremly compact PWM servo amplifiers that provide four-quadrant speed control of any trapezoidal servo motors with hall-effect feedback. The Amplifiers are conceived for regulation of brushless DC motors. The power supply transform AC voltage into DC voltage. From DC voltage the amplifier is producing the current for the motor. Hall sensors are producing necessary information concerning rotor position. Output current is PWM controlled and due to high chopper frequency a large bandwidth and dynamic are granted.

| The speed is
proportional to the frequency of the output current |
| The direction of
rotation corresponds to sense of rotation of the output current |
