	The paper presents calculation and construction of gearless driver for lift door. Driver consists of DC brushless motor and electronic controlling circuit. Basic constructing assumptions were low turning velocity, high nominal and starting torque and low cogging torque. Motor control was realized by microcontroller MB91F267 fitted with u-DSP core. Working conditions required the application of algorithms of speed feedback with assumed trajectory of door movement. Cost reduction forced the authors to give up the module of continuous measurement of speed and utilize existing rotors position sensors. The paper presents also images of the motor, controlling electronic circuit and the whole system mounted in lift door. Presented solution was successfully tested in real object.
