70mm DC Spur Gear Motor includes 70SS3525, 70SS3530, 70SS3540 Dc Spur Gear Motor. 70Mm Dc Spur Gear Motor also has a square gearbox design. For some models, 70mm DC Spur Gear Motor might has less torque than 50Mm Dc Spur Gear Motor, but when some design has a vertical space limit, 70mm dc spur gear motor would be a good choice.
70mm dc spur gear motor has 3 types gear stages as following:
For the 3 stages gearbox, it has 54, 73 gear ratios;
For the 4 stages gearbox, it has 217, 293 gear ratios;
For the 5 stages gearbox, it has 564, 763 gear ratios;
Number of stages | 3 | 4 | 5 |
Reduction Ratio | 54, 73 | 217, 293 | 564, 763 |
Gearbox length(L) mm | 15 | 15 | 15 |
Breaking torque(kg f.cm) | 30 | 50 | 100 |
Gearbox efficiency | 73% | 65% | 59% |
70mm dc spur gear motor is usually applied in some home appliance like automatic sweeping machine, parking devices and so on.
