planetary gear motor

Ever-Electricity DC Planetary gearmotors are an inline choice for low speed, high torque, and/or variable load requirements. These equipment motors are created for intermittent duty operation since the planetary gearbox construction provides the highest performance and best output torque of most our quickness reducers. DC motors combined with planetary equipment reducers are ideal for products in the agricultural and structure industrial sectors. With 18 ratio alternatives ranging from 5:1 to 1000:1, we’ve a DC planetary gearmotor answer to suit your needs.
For a smaller footprint and quieter gearbox design, look for our I-series Planetary gearmotors. Body sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1.
1/25 to 3/8 HP
12, 24, 90, 130, 180VDC, 115 FWR
.5 – 475 RPM
3.5 – 950 in-lb rated torque
Frame Size 60, 80, 108 mm
5:1 – 1000:1 standard ratios
Regular brush life of 2000+ hours (varies by application)
This is a simple ~140RPM (no load), DC planetary gearmotor. This electric motor is great for different applications such as for example robotics, electric locks, home automation, and tiny actuators.
The supply voltage range is 6VDC – 24VDC with the polarity marker at the base of the motor. The planetary gear package, mounted on top of the motor casing, gives this motor a comparatively large stall torque because of its size. The entire body of the engine is made of metal, apart from the set of planet gears on the primary input equipment set, which will be plastic.
This planetary gearmotor comes with an over-all body dimension of 76.1mm length with a 22mm diameter as the travel shaft is 12mm in length and 6mm in diameter.
Benefits of using planetary equipment motors in your projects
There are numerous types of geared motors that can be utilised in search for the perfect movement in an engineering project. Considering the technical specs, the mandatory performance or space restrictions of our design, you should consider to work with one or the various other. In the following paragraphs we will delve on the planetary equipment motors or epicyclical equipment, so you will know carefully what its advantages are and discover some successful applications.
The planetary gear models are characterized by having gears whose disposition is quite not the same as other models such as the uncrowned end, cyclical (step by step) or spur and helical gears. How could we classify their elements?
Sun: The planetary gear motor central gear. It has a greater size and rotates on the central axis.
The earth carrier: Its objective is to hold up to 3 gears of the same size, which mesh with the sun gear.
Crown or band: an outer ring (with teeth about its inner part) meshes with the satellites and contains the complete epicyclical train. Furthermore, the core can also become a centre of rotation for the outer ring, and can easily change directions.
For accuracy and dependability, many computerized transmissions currently use planetary gear motors. If we discuss sectors this reducer gives great adaptability and can be utilised in very different applications. Its cylindrical condition is very easily adaptable to thousands of areas, ensuring a large reduction in an extremely contained space.
Regularly this sort of drives can be utilized in applications that want higher degrees of precision. For example: Industrial automation devices, vending equipment or robotics.
What are the main features of planetary gear motors?
Increased repeatability: Its better speed radial and axial load offers reliability and robustness, minimizing the misalignment of the gear. In addition, uniform tranny and low vibrations at distinct loads provide a perfect repeatability.
Best precision: Most rotating angular stability increases the accuracy and stability of the movement.
Lower noise level since there is more surface contact. Rolling is a lot softer and jumps are virtually nonexistent.
Greater durability: Because of its torsional rigidity and better rolling. To improve this feature, your bearings lessen the losses that would take place by rubbing the shaft on the package directly. Thus, greater effectiveness of the apparatus and a very much smoother operation is achieved.
Very good degrees of efficiency: Planetary reducers provide greater efficiency and thanks to its design and internal layout losses are minimized throughout their work. Actually, today, this kind of drive mechanisms are those that provide greater efficiency.
Improved torque transmission: With an increase of teeth connected, the mechanism is able to transmit and withstand more torque. In addition, it does it in a more uniform manner.
Maximum versatility: The mechanism is within a cylindrical gearbox, that can be installed in almost any space.
What regulations connect with planetary gearboxes?
Understand that each supplier sets its own steps when presenting the operating time of your gears or the maximum torque they could 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: Component II talks about the design of the output shafts of these geared motors according to several specifications.
