| Compact, and yet extremely powerful, are the units of the 300 series. Their planetary drive train makes them the ideal choice for all the severe duty applications where shock loadings and impacts are more the rule than the exception. The product configuration is highly versatile, due to several options as far as the mounting, the gear layout, the output shaft and the motor interface. All the features are available for each of the 16 finely spaced frame sizes, spanning over the 1.000 - 450.000 Nm torque range. Finding the perfect match to any drive problem is therefore more than a wish, it is something users can safely rely on - always. |

By using a flexible ring-gear the planetary gears achieve a backlash of < 1 minute of arc without requiring an additional backlash adjustment mechanism. Until now highly accurate gears and / or an additional adjustment mechanism were necessary to minimize backlash. Tight gear engagement for conventional planetary gears leads to torque ripple and a worsening of noise and wear characteristics. To avoid this problem the new HPG series features a flexible internally toothed ring-gear, thereby exploiting many years of Harmonic Drive experience with thin-walled components. The flexible ring-gear ensures that backlash is minimized and that all planet gears share the load equally.
Advantages:
- Backlash less than 1 minute of arc
- High moment stiffness
- High efficiency
- Repeatability better than 20 seconds of arc
- Easy motor assembly |

Planetary Gearboxes:
• Magnifies torque
• increases the accuracy of the application
• reduces speed
• high ratios in 1 stage
• output and input rotate in the same direction
• back-driveable etc. |

| The Sumitomo Cyclo drive is unsurpassed by any other inline drive available in the market today. Cyclo's unique epicycliodal design has advantages superior to speed reducers using common involute tooth gears. Cyclo components operate in compression, not in shear. Unlike gear teeth with limited contact points, a Cyclo has two thirds of its reduction components in contact at all times. This design enables Cyclo speed reducers and gearmotors to withstand shock loads exceeding 500% of their ratings, and provide exceptional performance, reliability and long life in the most severe applications. |

GP 22 S and GP 32 S modular spindle drives.
Mechanical engineering often faces the task of converting rotational movements into powerful linear movements. The associated development costs can now be cut dramatically by using modular spindle drives in maxon motor's modular system. The GP 22 S and GP 32 S gearheads, specifically adjusted for spindles, are designed to withstand high loads, and the special spindle intake means that customer-specific spindles can be assembled easily which shortens supply times.
There are three different standard spindle types to choose from: metric spindles, trapeze spindles and spherical rotating spindles. The spindles are available as steel or ceramic variations and in any length up to 200 mm. Spindle nuts to match are supplied.
Gearheads, motors, encoders and controllers from maxon's standard program are used to drive the spindles. The individual components of the spindle drives are all compatible to help create highly effective drive solutions. For the time being, modified planetary gearheads are available in two different sizes, with diameters of 22 mm and 32 mm. Reduction ratios of 3.7:1 to 1093:1 provide maximum torques of 6 Nm and speeds of up to 1600 min-1. The additional axial bearings of these gearheads can also withstand powerful axial forces from the spindles. |
