Motor control systems, foldable partitions employing motor control systems, methods of monitoring the operation of electric motors and foldable partitions
Abstract:
Motor control systems comprise a motor control circuit, a processing circuit operably coupled to the motor control circuit, and a current sensor operably coupled to the processing circuit. The current sensor may be configured to sense a current and to convey a signal to the processing circuitry proportional to an amount of current sensed. The processing circuitry may be configured to sample the signal to obtain a plurality of current values, to store the plurality of current values and to generate an operation profile from the plurality of current values. Folding partitions comprising motor control systems are also disclosed, as well as methods of monitoring an operation of an electric motor and of monitoring for an obstruction of a folding partition.
