Three Motor Automatic Reverse Stereo Tape Deck
GX-210D features 3-motor drive mechanism includes self-lubricating Hysteresis Synchronous Motor
To match the lasting performance of the GX Head, the GX-210D is equipped with Akai's unique self-lubricating capstan motor. The installation of two oil circulating mechanisms with cellulose fibres within the interior of the motor provides long lasting, trouble-free operation. Oil circulating speed is adjusted naturally according to motor revolutions and temperature, and because shaft rotation is always smooth and stable, various mechanical troubles resulting from oil circulation suspension do not occur. Further, these unique cellulose fibres also function as filters to keep the oil clean during the circulating process, adding to the motor's epoch-making longevity. Two highly efficient outer-rotor motors for supply and take-up reel drive assure consistent and smooth tape travel and ideal starting torque.
