EMC (Electronic Health Compatibility) of centrifuges hinges on the motor drive. For solutions using inverters to drive AC motors, dedicated inverter filters should be installed at the inverter's input and output terminals. For solutions using brushless DC motors, the driver should undergo filtering similar to other devices (ferrite beads, capacitors). Motor speed feedback signals (e.g., Hall effect sensors, encoders) should be shielded. Imbalance detection sensor signals (typically vibration sensors) must be connected via shielded wires and passed through a bandpass filter amplifier to suppress unrelated frequency interference. The centrifuge's metal casing should be grounded, and it should be placed away from sensitive instruments.
