Miniature gear motor range

For the 25 W speed-regulating entry, the table lists 0.07 N·m motor torque at 90 rpm and 0.19 N·m at 1,400 rpm for 50 Hz operation. Reducing motor speed with the controller therefore does not preserve full-speed rated torque. Calculate the load at the chosen motor speed and reduction ratio; the fixed-speed gearbox table above cannot by itself validate a 90 rpm motor operating point.

TAILI distinguishes gear-shaft matching for 2–250K, 300K and 400–600K, and warns against heavy loads above 300K. It also offers a 10:1 intermediate reducer for additional reduction. Include that reducer explicitly in the order and obtain the complete assembly’s permissible torque and dimensions. Adding another reduction stage is not proof of ten times the allowed output torque.

The 25 W GK fixed-speed assembly is dimensioned 159.5 mm in body length, while its speed-regulating version is 170.5 mm. The corresponding brake assemblies are 200 and 211 mm. The illustrated gearbox output shaft is 10 mm diameter with 30.5 mm projection; the separate round-shaft motor drawing shows an 8 mm shaft. Use the gearbox-output drawing for the driven coupling, rather than the bare motor’s shaft size.

The illustrated 80 mm front uses a 66.5 mm square mounting pattern. A terminal-box version adds space above the motor, and a speed-regulating version includes a rear section. Send the available length, overhead clearance and desired shaft orientation with the enquiry. Those 80 mm drawings do not establish the dimensions of the 60, 70, 90, 104 or 120 mm catalogue alternatives, or the right-angle range.

For the listed single-phase examples, the capacitor entries are 6 µF/250 VAC at 110 V and 2 µF/450 VAC at 220 V. Have the exact motor and capacitor combination confirmed, particularly when replacing an existing assembly. Include line frequency, direction changes, continuous or timed running, required output rpm, running and starting load, and whether a brake or speed controller is part of the supply.
