Multifunction station for motor test bench

Power supply functions 
• DC outputs are galvanically isolated from each other as well as from the mains by NF EN 61558 isolation transformers
• The continuous power is produced by a Graëtz bridge (ripple 4%)
• The auxiliary DC is full-wave rectifier whose ripple rate varies with the load

Speed control functions
• Speed control by potentiometer 
• Start/Stop by button 
• Parameterization via the control console (choice of rotation, acceleration ramp, fault reset ...) 
• Setting frequency 0-400Hz

Brake control
• Brake control by potentiometer

Functions measurement of mechanical quantities 
• Display of mechanical torque in N·m (5V range for 20 N·m)
• Display of rotational speed in rpm (10V range for 1000 rpm)
• Display of mechanical power in watts

Functions measurement of balanced electrical quantities 
• Measures continuous, single-phase, and balanced three-phase TRMS (true root mean square) values.
• Simultaneous display of electrical quantities: voltage, current, active power, reactive power, and cos phi.
• Maximum voltage: 700V AC/DC
• Maximum current: 20A AC/DC

Data acquisition functions
• Real-time visualization of curves for each parameter as a function of time.
• Data acquisition and storage in .csv format onto a USB flash drive (not included), allowing for further processing in the spreadsheet software of your choice.
• Following a short data acquisition period, it is also possible to display the speed variation curve as a function of the applied torque (X/Y graph) directly on the device.
• Curves can be exported to a spreadsheet program to perform calculations such as slip, efficiency, power factor (cos φ), etc.
