Motor gearboxes are exclusively planetary gears and have reduction ratios. The advantages of the gearboxes are that they have a service life of up to 30,000 hours, are maintenance-free and lubrication-free. They also have an extreme temperature resistance of -10°C to 90°C. The motor gearboxes are available in two different sizes. The flange size of 60mm is suitable for stepper motors and EC/BLDC motors in size NEMA 23 and 24 - flange dimensions 56mm and 60mm. The motor gearbox with a flange size of 90mm is suitable for the large NEMA 34 - flange size 86mm. For all gearboxes, a choice can be made between the reduction ratio: 3, 5, 10, 15, 20 and 40.
