  • Indirect temperature monitoring for thermal control of a motor in a printer
    Patent number: 8662620
    Abstract: In one embodiment, a method of operating a permanent magnet direct current (PMDC) motor in a printer has been developed. The method includes identifying that a temperature of the PMDC motor exceeds an operating temperature of the motor without the use of a direct temperature sensor. The PMDC motor operates at a reduced printing rate to prevent the motor from overheating.
