planetary gear motor

Ever-Electricity DC Planetary gearmotors are a great inline alternative for low speed, substantial torque, and/or adjustable load requirements. These gear motors are designed for intermittent duty operation since the planetary gearbox construction provides the highest proficiency and best result torque of all our velocity reducers. DC motors coupled with planetary equipment reducers are ideal for gear in the agricultural and engineering industries. With 18 ratio options ranging from 5:1 to 1000:1, we have a DC planetary gearmotor choice to fit your needs.
For a smaller footprint and planetary gear motor quieter gearbox design, look for our I-series Planetary gearmotors. Frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1.

This is a straightforward ~140RPM (no load), DC planetary gearmotor. This engine is great for different applications such as for example robotics, electric locks, home automation, and small actuators.
The supply voltage range is 6VDC – 24VDC with the polarity marker at the base of the electric motor. The planetary gear package, mounted together with the motor casing, gives this motor a comparatively large stall torque because of its size. The overall body of the electric motor is constructed of metal, with the exception of the set of planet gears on the primary input gear set, which will be plastic.
This planetary gearmotor comes with an over all body dimension of 76.1mm length with a 22mm diameter while the travel shaft is 12mm in length and 6mm in diameter.
Advantages of using planetary gear motors in work
There are lots of types of geared motors that can be utilized in search for an ideal movement in an engineering project. Considering the technical specs, the mandatory performance or space restrictions of our design, you should ask yourself to employ one or the additional. In the following paragraphs we will delve on the planetary equipment motors or epicyclical gear, and that means you will know completely what its positive aspects are and discover some successful applications.
The planetary gear systems are characterized by having gears whose disposition is quite different from other models such as the uncrowned end, cyclical (step-by-step) or spur and helical gears. How could we classify their elements?
Sun: The central equipment. It has a greater size and rotates on the central axis.
The planet carrier: Its objective is to hold up to 3 gears of the same size, which mesh with the sun gear.
Crown or ring: an outer ring (with teeth in its inner side) meshes with the satellites and contains the whole epicyclical train. Furthermore, the core may also become a center of rotation for the outer ring, allowing it to easily change directions.
For accuracy and stability, many automated transmissions currently use planetary gear motors. If we discuss sectors this reducer gives great versatility and can be used in very different applications. Its cylindrical shape is easily adaptable to an infinite number of areas, ensuring a large reduction in a very contained space.
Regularly this sort of drives can be utilised in applications that require higher degrees of precision. For instance: Industrial automation devices, vending equipment or robotics.
What are the primary features of planetary gear motors?
Increased repeatability: Its greater speed radial and axial load offers reliability and robustness, minimizing the misalignment of the gear. In addition, uniform transmission and low vibrations at different loads provide a perfect repeatability.
Ideal precision: Most rotating angular stability enhances the accuracy and stability of the movement.
Lower noise level because there is more surface area contact. Rolling is a lot softer and jumps happen to be virtually nonexistent.
Greater durability: Because of its torsional rigidity and better rolling. To improve this feature, your bearings lessen the losses that could appear by rubbing the shaft on the package directly. Thus, greater proficiency of the apparatus and a very much smoother operation is achieved.
Very good degrees of efficiency: Planetary reducers deliver greater efficiency and thanks to its design and internal layout losses are minimized throughout their work. Actually, today, this kind of drive mechanisms will be those that provide greater efficiency.
Increased torque transmission: With more teeth in contact, the mechanism has the capacity to transmit and withstand more torque. In addition, it does it in a more uniform manner.
Maximum versatility: The mechanism is contained in a cylindrical gearbox, which may be installed in nearly every space.
What regulations apply to planetary gearboxes?
Understand that each company sets its own actions when presenting the operating time of the gears or the utmost torque they are able to bear. Nevertheless, we are able to find certain restrictions governing these parameters.
– ISO 6636 for gears.
– DIN ISO 281: With the rules that helps to make a correct calculation of the bearings.
– ISO 9409: Portion II talks about the design of the output shafts of the geared motors according to different specifications.
