Currently, robot arms that move in three dimensions require at least six conventional motors, all linked together, to position and orient an object.
While a conventional motor is constructed from thousands of parts, the Turbozám only has around 20.
Minolta also uses piezoelectric actuators rather than conventional motors to move the chip around.
They have several advantages over conventional motors:
Propulsion may involve conventional on-board electric motors, linear motors or cable traction.
The active portion of the motor consists of a conventional electric motor winding stretched out under the vehicle.
As they have no moving parts, a LIM-powered vehicle would be more reliable than one using a conventional motor.
Usually, electrostatic motors are the dual of conventional coil-based motors.
Later four-cylinder engines adopted the more conventional (pre-engaged) separate starter motor and alternator.
Most conventional electric motors include ferrous material composed of laminated electrical steel.
