Review SAYAMA Coreless Micro 20mmmm Ratio209 Pole Gearmotor-31 Precision

The Coreless Micro 20mm Ratio-209 Overall-Ratio-209 Pole 12 Gearmotor-31 is a remarkable piece of engineering, designed for precision applications that require high torque and compact size. Measuring just 20mm in diameter, this gearmotor is incredibly small, making it perfect for applications where space is limited.

The gearmotor features a coreless design, which eliminates the need for a permanent magnet, reducing weight and increasing efficiency. This design also allows for operation in magnetic fields, making it an excellent choice for robotics and automation applications.

The ratio of this gearmotor is 209:1, meaning for every 209 rotations of the input shaft, the output shaft makes one rotation. This high gear ratio provides a significant increase in torque, making it capable of handling heavy loads.

The gearmotor is equipped with 12 gears, which further enhances its torque output and provides a smooth operation. The precision of the gears is maintained at a high level with the use of 31 precision bearings, ensuring the gearmotor runs quietly and smoothly, even under heavy loads.

The Coreless Micro 20mm Ratio-209 Overall-Ratio-209 Pole 12 Gearmotor-31 is an ideal choice for miniature robots, drones, and other applications where high torque and compact size are essential. Its coreless design, high gear ratio, and high-quality bearings make it a reliable and powerful component for precision applications.

However, its limited speed and high cost may make it less suitable for applications that require high speed or have a tight budget. Overall, if the specifications of the gearmotor match the requirements of your project, it can be a great investment.

If you are looking for a powerful and precise gearmotor for your robotics or automation project, the coreless micro 20mm ratio-209 overall-ratio-209 pole 12 gearmotor-31 precision is a great option to consider. However, make sure to compare it with other options on the market to ensure that it meets your specific needs and budget. Additionally, consider the compatibility of the gearmotor with your control system and other components of your project to ensure a smooth and successful integration.

Details:

It is a plus if the magnets are samarium cobalt or neodymium as rare earth magnets are a lot more powerful and expensive than along magnets and double or triple motor torque. 4mm gear head has 2mm shaft and quadruples the torque. See spec sheet for back emf factor.

This is motor will crank about 12,000 rpm at 12 volts . This listing is for the motor equipped with neodymium magnets which have 35 times the power of along and as a result a motor delivers 2 or 3 times the torque of an equal motor with along magnets this motors torque is in the factory spec sheet and micro locomotion has a stall torque comparison chart and torque watches to measure stall torque of motors. See other listings for the rolls Royce class of motors described as following Swiss made precision rare earth re10 10mm by 24mm coreless single 1mm shaft motor without the gear head. 5mm 2mm or 2.

See other listings for 10mm by 26mm cylindrical and 10 by 12 by 20mm and 24mm motors with and without the gear heads. The lack of an iron core coreless motor means zero clogging and when power is interrupted it coasts and does not stall. See other listings for the 10 by 12 by 15 double shaft mashing. It flywheels a few seconds and that's enough to coast you through switch work for several inches to prevent stalling the steam or diesel locomotive through dirty or rough track work with or without flywheel.

Works with CDC in newer high frequency decoders. 33 or 3 to 1 ratio up and also planetary systems 4 to 1 and up. When I get time will list the motor only and the gearmotor with reduced gear ratio. Due to design which more closely follows the magnetic hysteresis and uses it to develop the most power from the magnetism available.

Available with gear heads in shaft in Remember I have some flabbier Sayama makes 1212 too and some Macon 1217 coreless motors and gearmotor. This also works out to about 1 mile per hour for each 1 inch of driver diameter 45 inch drivers should go 45 miles per hour at scale speed 60 inch drivers go 60 mph.

Check other listings or inquire about substitutions available if you are winning bidder. These motors run about 100 from the us importer. Lots of watchmaking. I bought a bunch of 1mm and screws and when I get er perfected I will list these in separate listing.

Available with spur or planetary gear heads gp10 or the other Macon the gear heads have 2 or 3mm shaft and ratios available from 3,44 or 6 to 1 up all coreless can motors will coast when power is interrupted and have zero clogging at low speeds but with a flywheel it will coast several seconds no load and a lot longer with a flywheel check other listings for the gear head model's this is a single shaft. These Swiss precision gearmotor systems are for the advanced hobbyist who has the experience to understand the engineering of locomotive scale speed and novice hobbyists may find the techno babble over there heads. 4mm it has neodymium magnets which are 35 times the power of along and in a motor double or triple stall torque with a 4 to 1 planetary gear head these motors then have a 2mm shaft and 4 times the torque and for he robot guys ratios up to 1000 to Also check other listings for the tiny tots and mighty mite 6 and 8mm gearmotor.

This is a coreless rolls Royce quality can motor for brass or plastic loco diesel or steam loco. The re10 1024 is also available in 1024 double 1mm shafts and with a gear head and or an encoder.

Rpm per volt because of their efficiency these motors will not load down on hill or under heavy loads and your pack will deliver more volts for speed high motors eat up your volts eating up your speed. 5/2 or 1331 motors and gearmotor and also economy flat can 10 by 12 by 11 or 13 or 15 single and double shafts. The 1024 is available with an integral encoder and ribbon cable.

Efficiency is rated over 75 converting amps to stall torque. The brushes are gold and the commutator is made of silver.

Macon uses neodymium in their re series and neodymium rare earth magnets double or triple the torque and this motor is also available in a 1024 size with double shafts size and both 1024 and 1017 are available with gear heads 4 to 1 ratio or 16 to 1 multiples of 4 is 64 then 256 and 1024. At top speed or 5 to 6 piston strokes per second.

Rpm per volt these motormen are known as Goolagong or bell armature in Europe and used in Rico TRX matrix and Marlin and are available in sizes 6mm to 40 and gear heads grebe n scale, ho, hon3, nn3, sn3, on3,scale, o scale, narrow gauge, standard gauge, see below see below see below coreless motors flywheel when the power is interrupted so takes you through dirty track and prevents stalling. So multiply that times your gear ratio to find out what your motor drive shaft speed should be. This is a listing for one precision coreless 5 pole 12mm by 20mm motor with single 2mm shaft.

If link does not work go to Macon dot motors are available by special order with extra long double shafts. See spec sheet for back emf factor. For motion control engineers the 1024 has an encoder and ribbon cable.

With just a small flywheel on the 1mm shaft performance is excellent. You can't do that with a can iron core motor. Removing gear head and pulling the pinion gear leaves a nifty 1220 coreless motor with 1mm shaft and sleeves are available. Kits are available for all major brass locomotives see my other listings.

The 1mm shafts can be sleeved to Some of the flabbier motors pictured have a planetary 4 to 1 gp10 Macon gear head with a 2mm shaft extension and its available If you like your locomotive to start like the prototype and chug smoothly through rough track and dead spots this is the motor for you. I can mount the 8/1 flabbier gear head 4 to 1 ratio and will list those when I get time.

Many more precision coreless motors and Swiss gear heads available from the motorman. The gear ratio is 207 to 1 making this little guy ideal for shays and critters. Factory spec sheets are available at Macon dot com.

Happy trains. Making it as powerful as a much larger motor and more powerful than the larger 1219 motors because of the neodymium magnets. Flywheels are 5 each.

Flywheels available for 5 custom for your size requirements. This is the precious metal version which has gold and silver brushes and commutation. 4mm shaft extension see other micro locomotion listings for 1319 remix 1320 will accept a 10mm gear head. volts and amps vary inversely under load.

See other listing for units with gear heads. This is a mathematical coincidence of diameter times pi times rpm gives speed in inches divide by 12 and that's feet per minute.
