Abstract
An electric motor unit with continuous current containing a connection plate and a card that carries electronics for the control of the motor. The card also contains electronics to monitor the current in order to detect the blockage of the motor's rotor and electronics to control the power supply of the motor. The card and/or the plate carries devices to sense temperature. The electronics to control the power supply are linked to the device(s) sensing temperature, as well as to the electronics monitoring the current. The control electronics cuts off the power supply of the motor when blockage of the motor's rotor is detected and a temperature measured by at least one of the devices reaches a high threshold value and reestablishes the power supply of the motor when the temperature is at or below a low threshold value.
