planetary gear motor

Ever-Electricity DC Planetary gearmotors are an inline option for low speed, excessive torque, and/or adjustable load requirements. These gear motors are created for intermittent duty operation for the reason that planetary gearbox configuration provides the highest proficiency and best output torque of all our quickness reducers. DC motors combined with planetary gear reducers are ideal for tools in the agricultural and building sectors. With 18 ratio options which range from 5:1 to 1000:1, we’ve a DC planetary gearmotor choice to fit your needs.
For a smaller footprint and quieter gearbox design, search 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

Frame Size 60, 80, 108 mm
5:1 – 1000:1 standard ratios
Standard brush life of 2000+ hours (varies by application)
This is a simple ~140RPM (no load), DC planetary gearmotor. This electric motor is great for several applications such as robotics, electric locks, household automation, and small actuators.
The supply voltage range is 6VDC – 24VDC with the polarity marker at the bottom of the motor. The planetary gear package, mounted together with the motor housing, gives this motor a comparatively large stall torque for its size. The entire body of the engine is made from metal, apart from the set of planet gears on the 1st input gear set, which happen to be plastic.
This planetary gearmotor has an over all body dimension of 76.1mm length with a 22mm diameter as the travel shaft is 12mm long and 6mm in diameter.
Benefits of using planetary equipment motors in your projects
There are many types of geared motors that can be utilised in search for the perfect movement within an engineering project. Considering the technical requirements, the mandatory performance or space constraints of our design, you should ask yourself to work with one or the additional. In this article we will delve on the planetary equipment motors or epicyclical gear, so you will know carefully what its advantages are and find out some successful applications.
The planetary gear models are characterized by having gears whose disposition is quite different from other models like 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 much larger size and rotates on the central axis.
The planet carrier: Its objective is to carry up to 3 gears of the same size, which mesh with the sun gear.
Crown or ring: an outer band (with teeth on its inner part) meshes with the satellites possesses the whole epicyclical train. Furthermore, the core can also become a middle of rotation for the outer ring, allowing it to easily change directions.
For accuracy and reliability, many programmed transmissions currently use planetary gear motors. If we talk about sectors this reducer provides great versatility and can be utilised in completely different applications. Its cylindrical condition is without difficulty adaptable to an infinite number of areas, ensuring a huge reduction in an extremely contained space.
Regularly this type of drives works extremely well in applications that want higher degrees of precision. For instance: Industrial automation equipment, vending equipment or robotics.
What are the main benefits of planetary gear motors?
Increased repeatability: Its higher speed radial and axial load offers planetary gear motor reliability and robustness, minimizing the misalignment of the gear. In addition, uniform transmitting and low vibrations at numerous loads provide a perfect repeatability.
Excellent precision: Most rotating angular stability increases the accuracy and reliability of the movement.
Lower noise level because there is more area contact. Rolling is much softer and jumps will be virtually nonexistent.
Greater durability: Due to its torsional rigidity and better rolling. To improve this feature, your bearings help reduce the losses that could happen by rubbing the shaft on the field directly. Thus, greater performance of the apparatus and a much smoother procedure 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. In fact, today, this type of drive mechanisms are those that offer greater efficiency.
Improved torque transmission: With an increase of teeth in contact, the mechanism will be able to transmit and withstand more torque. In addition, it does it in a far more uniform manner.
Maximum versatility: It is mechanism is contained in a cylindrical gearbox, which may be installed in almost any space.
What regulations apply to planetary gearboxes?
Take into account that each company sets its own actions when presenting the operating time of the gears or the maximum torque they could bear. Nevertheless, we can find certain restrictions governing these parameters.
– ISO 6636 for gears.
– DIN ISO 281: With all the current rules that helps to create a correct calculation of the bearings.
– ISO 9409: Portion II talks about the look of the output shafts of these geared motors according to numerous specifications.
