8mm Stepper Motor Planetary Gearbox Small Size With MIM Technology
This motor is 8mm diameter stepper motor with planetary gearbox on
top.
There are two levels on the gearbox, gear ratio of first level is
4:1, and the gear ratio on the second level is 5:1, thus total
ratio is 4*5=20:1
There is a flange in the middle for assembly. If customers think it
takes too much of space, we could remove it for mass production in
the future, and it does not affect motor’s parameters.
This motor does not have output shaft, it has a blind hole instead.
Customers can design a output shaft, with the end fits in the blind
hole, and then insert it in.It would be equivalent as a regular
output shaft.
| Model No. | SM08PG |
| Motor diameter | 8 mm |
| Drive voltage | 5V DC |
| Coil resistance | 14Ω±10%/phase |
| Number of phase | 2 phases (bipolar) |
| Step angle | 18 degrees/20 |
| Gearbox type: | Planetary gearbox |

This planetary gearbox is specifically design drawing micro
electronic products such as mobile phone, camera and other small
sized products.
It’s a 2 levels gearbox, and the gears and other components inside
are made from Metal injection Molding technique (MIM technology).
MIM technology use injection method to produce metallic parts, just
like the way we product plastic with injection mold. It can produce
high precision metal parts with small size and high precision,
which is critical for a mini sized gearbox.
But the equipment of MIM technology is expensive, thus the order
quantity of it is higher. Otherwise the cost on each piece of
product is too long. So minimum order quantity of MIM is higher, in
order to lower average cost.
1.The power input part of the standard stepper motor is available
in the form of FPC, FFC, PCB cable, etc.
2.For output shaft, we have two different types of standard
shafts:D shaft and screw shaft. If a special axis type is required,
we can also customize it, but there is an additional customization
cost.
3.8 mm diameter permanent magnet stepper motor with 10*8 mm gear
box. The gear box has high precision, high efficiency and low
noise, which makes the product have good reliability.
Geared stepper motors, widely used in Smart home, personal care, home appliance equipment, smart medical equipment, smart robot, smart logistics, smart cars, communication equipment, smart wearable devices, consumer electronics, camera equipment, and other industries.
1. Coil resistance/rated voltage: The coil resistance is
adjustable, the higher the resistance, the higher the rated voltage
of the motor.
2. Bracket design/slider length: If customers want longer or
shorter bracket, there are special design, such as mounting holes,
it is adjustable.
3. Slider design: the current slider is brass, it can be replaced
with plastic to save cost
4. PCB+cable+connector: PCB design, cable length, connector pitch
are adjustable, can be replaced with FPC according to customer's
need.
Lead time for samples:
Standard motors in stock: within 3 days
Standard motors not in stock: within 15 days
Customized products: About 25~30 days (based on complexity of
customization)
Lead time for building a new mold: generally about 45 days
Lead time for mass production: based on order quantity
Packaging:
Samples are packed in foam sponge with a paper box, shipped by
express
Mass production, motors are packed in corrugated cartons with
transparent film outside. (shipping by air)
If shipped by sea, product will be packed on pallets
On samples and air shipping, we use Fedex/TNT/UPS/DHL. (5~12 days for express service)
For sea shipping, we use our shipping agent, and ship from Shanghai
port. (45~70 days for sea shipping)
1.Stepper motor how to use the curve exponential control speed?
Exponential curve, in the software programming, first calculated
time constants stored in the computer memory, work pointing to the
selection. Usually, the acceleration and deceleration time to
complete the stepper motor is 300ms or more. If you use too short
acceleration and deceleration time, for the vast majority of
stepper motors, it will be difficult to achieve high-speed rotation
of stepper motors.
2.What are the commonly fitted gearboxes for stepper motors?
Stepper motors are assembled with reducers such as planetary
reducers, worm gear reducers, parallel gear reducers, and filament
gear reducers.
