22-mm Motors’ Small Size Suits It To Medical Equipment

Well suited for a variety of medical applications, the A-max 22-mm diameter motors are precision devices often used in print heads, pumps and measuring instruments. The motors’ patented rhombic moving-coil design provides for long life, low electrical noise, fast acceleration and high efficiency. The ironless rotor allows for zero cogging and simple, accurate control circuits. Available with either precious metal brushes or graphite brushes, the motors’ power ratings range from 3.5W to 6W. Options include ball bearings or sleeve bearings and terminals or leads. Motor length is 31.9 mm (1.26") and weight is 54g (1.9 oz.). Several different windings are available to match desired speed with available voltage. Maximum continuous torque from the motor alone is up to 7.5 mNm (1 oz.-in.). Matching gearheads offer ratios ranging from 4.4:1 to 4592:1 capable of delivering 1 Nm (141.6 oz.-in.) of continuous torque.
