Abstract
A laboratory sample distribution system is presented. The system comprises carriers to carry sample containers. Each carrier comprises a magnetically active device. The system comprises a transport plane to support the carriers and electro-magnetic actuators stationary arranged below the transport plane. The actuators move the carriers on top of the transport plane by applying a magnetic force to the carriers. The system comprises a control device to control the movement of the carriers on top of the transport plane by driving the actuators such that the carriers move along corresponding transport paths simultaneously and independently from one another and a sensor to measure supply currents and/or supply voltages. The actuators are supplied with electrical energy based on the supply currents and/or the supply voltages. The system comprises a monitoring device coupled to the sensor. The monitoring device monitors the actuators temperature based on the measured supply currents and/or supply voltages.
