<p>A hub (37), fitted to the rotor spindle, supports a flat disc (38) at whose periphery are several vanes (36) whose axial length is at least that of the hub. Thus cavities (a, b) are formed above and below the disc. These provide increased speed of rotating. The housing is pref. made in two parts. The air inlet channel in the housing has a cavity (9) which contains a length of lubricant-soaked wick. The air stream carries the lubricant into the motor. The air outlet channel has a constriction at one point. The back pressure so induced increases the motor speed. The motor hub (37) is enclosed between the two ball bearings (21, 22) that carry the spindle.</p> |
