VSM1519 is a precision micro stepping motor. Its output uses M3 screw to perform linear movement and generate thrust, which can be directly used as an actuator to achieve the actions required by customers.
The basic angle of the stepping motor is 18 degrees, and the motor runs 20 steps every week. Therefore, the displacement resolution can reach 0.025mm, so as to achieve accurate control
The icon of motor input part is light, but it can be changed to FPC cable, PCB and other forms according to customer requirements
At the same time, we can complete the corresponding drive system to meet customer needs!
Our team has more than 10 years of experience in the design, development and production of micro motors, so we can develop and design products according to the special needs of customers!
Customer demand is the direction of our efforts, please feel free to contact

ApplicationAbout Micro stepper motor

Our micro stepper motors generally have 18 degrees step angle.(Full step driving)
That means it takes 20 steps to rotate one turn.
Motor’s step angle is related to internal stator’s design.
We have micro stepper motors with different diameters, and motor’s torque is related to its size.
Here is relationship between motor’s diameter and torque(with suitable running frequency, at rated voltage):
6mm motor: about 1 g*cm
8mm motor: about 3g*cm
10mm motor: about 5 g*cm
15mm motor: about 15 g*cm
20mm motor: about 40 g*cm


Motor’s speed is determined by driving frequency, and it has nothing to do with load (unless it’s losing steps).

Due to high precision speed control of stepper motors, with a driver controlled stepping you can achieve very precise positioning and speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.

Customization service

Motor’s design can be adjusted based on customer’s requirement including:
Motor’s diameter: we have 6mm, 8mm, 10mm, 15mm and 20 mm diameter motor
Coil resistance/ rated voltage: coil resistance is adjustable, and with higher resistance, motor’s rated voltage is higher.
Bracket design/ lead screw length: if customer want the bracket to be longer/short, with special design such as mounting holes, it’s adjustable.
PCB + cables + connector: PCB’s design, cable length and connector pitch are all adjustable, they can be replaced into FPC if customers require.

Lead Time and Packaging Information

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

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

1.Are you a manufacturer?
Yes, we are a manufacture, and we produces mainly stepper motors.

2.Where is your factory location? Can we visit your factory?
Our factory is located in Changzhou, Jiangsu. Yes, you are very welcome to visit us.

3.Can you provide free samples?
No, we don’t provide free samples. Customers won’t treat free samples fairly.

4.Who pays for shipping cost? Can I use my shipping account?
Customers pay for shipping cost. We will quote you shipping cost.
If you think you have cheaper/more convenient shipping method, we can use you shipping account.

5.What’s you MOQ? Can I order one motor?
We don’t have MOQ, and you can order only one piece sample.
But we recommend you to order a little bit more, just in case the motor is damaged during your testing, and you can have a back-up.

6.We are developing a new project, do you provide customization service? Can we sign a NDA contract?
We have over 20 years of experience in stepper motor industry.
We have developed many projects,  we can provide full set customization from design drawing to production.
We are confident we can give you few advice/suggestions for your stepper motor project.
If you are worrying about confidential issues, yes, we can sign a NDA contract.

7.Do you sell drivers? Do you produce them?
Yes, we do sell drivers. They are only suitable for temporary sample test, not suitable for mass production.
We do not produce drivers, we only produce stepper motors

Frequently Asked Question

1.The motor is four-phase six wires, and stepper motor driver as long as the solution four wires, how to use?
For four-phase six-wire motor, the two wires in the middle of the tap are left hanging, and the other four wires are connected to the driver.
2.The reasonable range of stepper motor heat generation:
The extent to which motor heat generation is allowed depends largely on the motor's internal insulation level. The internal insulation will only be destroyed at high temperatures (above 130 degrees). So as long as the internal does not exceed 130 degrees, the motor will not damage the ring, and the surface temperature will be below 90 degrees at that point. Therefore, the surface temperature of stepper motor in 70-80 degrees are normal. Simple temperature measurement method useful point thermometer, you can also roughly determine: with the hand can touch more than 1-2 seconds, not more than 60 degrees; with the hand can only touch, about 70-80 degrees; a few drops of water quickly vaporized, it is more than 90 degrees
