AutomatedPT offers a wide range of Sumitomo products. All but not limited to Sumitomo Gearmotors, Sumitomo Motors, as well as Sumitomo Variable Frequency Drives.

1. Sumitomo Cyclo gearmotors are the best in-line drives. The revolutionary Sumitomo Cyclo style and
design gives you well-performing, peaceful and highly effective operation which is much greater than
preceding tooth gear versions. The key ingredient to Sumitomo Cyclo’s peerless gearmotor effectiveness
and stability is the fact that about 70 percent of reducing parts are consistently in contact, when
compared to the geared types that will consistently utilize reduced teeth interaction.
Sumitomo Cyclo's electric motors, in contrast to any geared designs, normally work in compression as
opposed to shear, resulting in especially jolt proof capability. The expertise of Sumitomo Cyclo GearBox,
in conjunction with advanced apparatus and also package alternatives, deliver a vast range of available
possibilities.
Sumitomo Cyclo delivers a broad range of gearmotors available for quite a number of industrial
products.
These motors are offered in numerous layouts, ratios, dimensions, source horse power and fittings. It’s
all based on the prevailing gear engine circumstances. This brand are always dedicated to the creation of
the best quality transmission. They do cooperate with the Industrial Technical Research Institute so they
can come up with the most recent technological know-how in gear possibilities. All transmission motors
at Sumitomo Cyclo will be put together and machined within the manufacturing plant by a group of
expert specialists so as to sustain first-rate longevity, performance and reliability. In the long run, they
provide much longer endurance even while implemented in the harshest circumstances.
How to Choose a Sumitomo Cyclo Gearmotor.
The selection of a Gearmotor is dependent upon torque criteria and/or distinct performance at the
output shaft. A Sumitomo Cyclo gearmotor delivers excellent efficiencies compared to a diverse
spectrum of reduction ratios, often enabling the use of minimized energy demands (smaller horse
power motor) involvement without any forfeit of output shaft torque. You will be well guided in your
selection strategies any time you're deciding on the best motor unit for your own use.

2. The Details You Require To Start In your Selection Task.
In order to select the appropriate transmission motor for your purpose, it is important for you to be
aware of the subsequent requirements:
• Usage - the type of unit in question.
• The number of hours the device is being used each day.
• The rate (Revolutions Per Minute) and Motor horse power needed.
• Situation of mounting.
In case there happen to be any kind of particular elements in the situation or any other operation
demands, they should also be considered. The data will help within ascertaining your application’s
Service Factor.
Service Factors and How To Use Them.
Normally, gearmotors will be ranked in line with the functioning demands and unique conditions of the
system by means of using Service Factors that are defined by AGMA.
In the event the application happens to have operating circumstances which are exceptionally serious,
one may just keep to the technique of package choice. You might, thus, ascertain and use the Service
Factors so that you can make up for severe running conditions. The conventional ratings for Sumitomo

3. Cyclo tend to be based on a 10-hour regular service within specific conditions of uniform loads.
Typical Input Speeds of Sumitomo Cyclo Gear Electric Motors
The regular velocities are in general terms 1165 and 1,750 revolutions per minute. The Sumitomo Cyclo
preference criteria are in most cases based on 50, 580, 870, 1,165, 1750 RPM, and so on. By using input
velocities that tend to be non-standard, the torque and horse power ratings can change.
Constraints of Heat Capacity in Sumitomo Cyclo Gearmotors.
The Sumitomo Cyclo Gear Electric Motors, thanks to their friction-free and smooth action, could possibly
have heat ratings which go beyond by a large margin their mechanized norms, but generally minimizes
such conventional restraints because of the temperature. The conventional helical gears tend to be
rough and restrict comfortable operation.
The Sumitomo Cyclo Gear Electric Motors Drive Concept.
When the eccentric undertakes cycles, it might rotate one or more cycloid discs, according to the model,
around the ring gear housing’s internal area. The activity which results is not different from that of a disk
rolling within the interior of a ring. Because these cycloid discs rotate in a clockwise motion in the ring
gear, the cycloid discs themselves rotate in a counter-clockwise motion inside their own axes.
The cycloid discs’ cogs engage continuously with pins of a mounted ring gear. Backward turning is, for
this reason, produced at a particular rate. The speed rate usually depends on what amount of cycloid
teeth are located within the cycloid disc. For each and every cycloid disc, there is always at the very least
1 less tooth than there are rollers within the ring gear casing. This leads to the speed ratio being

4. numerically similar to the teeth within the cycloid disc. To sum up, as the high-speed shaft completes a
single revolution, the cycloid discs, consequently, rotate in the opposite course by a single tooth.
The revolution of cycloid discs is sent to the speed shaft by means of the rollers and pins protruding
through gaps in the cycloid discs. The speed shaft pins and occasionally the ring gear pins can also be
equipped with rollers to enable the torque transferring portions of the Sumitomo Cyclo gearmotor to
rotate smoothly.
Will Sumitomo Gear Electric Motors Perform With Inverters?
All active Sumitomo Gearmotors include magnetic wire which is corona proof, and this extends the
insulating endurance as well as enables the gearmotors to endure the voltage surges which tend to be
common among IGBT drives of adjustable frequency.
Is The Decision Process For Sumitomo Gearmotors Very Much Like Former Gearmotors?
The difference is normally restricted to applications which have large numbers across the line that starts
and stops. Because of the fact that Sumitomo Gearmotors have greater inrush current and more inertia
compared to previous integral motors, supplemental service aspects are provided to such applications
by using Sumitomo Gearmotors. The selection procedure for fractional devices has not changed.
Exactly What Is The Standard Insulation System?

5. The Sumitomo gearmotors even now have the Class F system. This restricts the temperature increase to
a Class B increase, where it fixes the allowable temperature rise to 80 degrees Celsius. It makes use of
insulating systems which are able to handle an upturn of 105 degrees Celsius as a way to increase
insulating life substantially.
Are Sumitomo Gearmotors Exchangeable With Earlier AF-Motors?
The new Sumitomo gearmotors without brake come with an identical ratio of 10:1 scale of torque
velocity as the old motor. Sumitomo Gearmotors are proficiency and dimensionally-wise different
therefore VFD re-programming is required.
