Power Electronic Racks

Power electronics racks

The power electronic racks were installed in 2002 based on a gift from Ameren UE. They are custom-built into a standard equipment rack and contain a controllable dc power supply, an ac-dc source panel, an inverter shelf, and a control and sensor interface. The power electronic components are configured for standard motor drive applications such as PWM dc drives and three-phase PWM ac drives. An external Microchip DsPIC microprocessor used to control the power electronics shelf.

Magtrol dynamometers

The Missouri S&T MotorLab is also equipped with various size Magtrol dynamometers for testing small motors (less than 4-kW). The largest of these is an HD-815-8 with a capability of up to 12,000-RPM and 28-Nm. The medium-sized Magtrol dynamometer is an HD-715-8 capable of operating at speeds of 25,000-RPM and torques of 6.2-Nm. The smallest is a model HD-500-8 with a capability of 20,000-RPM and 550-Nmm.

Software interface for the induction machines experiment

The meter panel contains six (6) channels of voltage and current sensors which are read by the PC. A LabView interface is used to display voltage and current waveforms as well as rms voltage, rms current, average real power, and average reactive power. The LabView interface has considerable capability and is frequently updated to include other functions such as power supply control.
