Description

This NEMA6 motor is a hybrid stepper motor with a relatively small diameter of 14mm.
This motor is a high precision, small size hybrid stepper motor with good looks and excellent performance. This stepper motor can be precisely controlled and programmed even without a closed loop encoder/no feedback system.
The NEMA 6 stepper motor has a step angle of only 1.8°, which means it takes 200 steps to complete one revolution.
The ambient temperature is-20℃~﹢50℃.
Life time is more than 6000 hours.
If you have any questions about the motor, please feel free to contact us for more professional support.

Application of Hybrid stepper motor

Due to high resolution of hybrid stepper motor’s (200 or 400 steps per revolution), they are widely used for applications requiring high precision, such as:
3D printing
Industrial control(CNC, automatic milling machine, textile machinery)
Computer peripherals
Packing machine
And other automatic systems requiring high precision control.

ApplicationNotes about hybrid stepper motors

Customers should follow the principle of “selecting stepper motors first, then select driver based on existing stepper motor”
It is best not to use the full-step driving mode to drive a hybrid stepping motor, and the vibration is bigger under full-step driving.
Hybrid stepper motor is more suitable for low-speed occasions. We suggest the speed does not exceed 1000 rpm (6666PPS at 0.9 degrees), preferably between 1000-3000PPS (0.9 degrees), and it can be attached with a gearbox to lower it’s speed. The motor has high working efficiency and low noise at suitable frequency.
Due to historical reasons, only the motor with a nominal 12V voltage uses 12V. Other rated voltage on design drawing is not exactly the most suitable driving voltage for the motor. Customers should choose suitable driving voltage and suitable driver based on own requirement.
When the motor is used with high speed or large load, it generally does not start at the working speed directly. We suggest to gradually increases the frequency and speed. For two reasons: First, the motor does not lose steps, and second, it can reduce noise and improve the positioning accuracy.
The motor should not work in the vibration area(below 600 PPS ). If it must be used at slow speed, vibration problem could be reduced by changing the voltage, current or adding some damping.
When the motor works below 600PPS (0.9 degrees), it should be driven by small current, large inductance and low voltage.
For loads with a large moment of inertia, a large size motor should be selected.
When higher precision is required, it could be solved by adding gearbox, increasing the motor speed, or using subdivision driving. Also a 5-phase motor(unipolar motor) could be used, but the price of the entire system is relatively expensive, so it’s rarely used.
Stepper motor size:
We currently have 20mm(NEMA8), 28mm(NEMA11), 35mm(NEMA14), 42mm(NEMA17), 57mm(NEMA23), 86mm(NEMA34) hybrid stepper motors. We suggest to determine motor size first, then confirm other parameter, when you select a hybrid stepper motor.

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

If we have samples in stock, we can ship out samples in 3 days.
If we do not have samples in stock, we need to produce them, production time is about 20 calendar days.
For mass production, lead time depends on order quantity.

Payment method and payment terms

For samples, in general we accept Paypal or alibaba.
For mass production, we accept T/T payment.
For samples, we collect full payment before production.
For mass production, we can accept 50% pre-payment before production, and collect the rest 50% payment before shipment.
After we cooperate order more than 6 times, we could negotiate other payment terms such as A/S (after sight)
