Product Description


Vic-Tech | 35mm NEMA14 geared stepper motor Description:


This is a high precision planetary gearbox stepper motor which is assembled from a range of 35mm (NEMA14) square hybrid stepper motors and cylindrical planetary gearboxes.


Motor lengths for this product generally range from 32.4 to 56.7mm, and special lengths can be customised. The longer the length, the higher the torque of the motor.


In addition, there are two options for the stepping angle of the motor. 0.9 degrees and 1.8 degrees, with the more common stepping angle being 1.8 degrees.


Reduction gearboxes are also available in many different speed ratios from 3.71 to 3729.5. Reduction gearboxes with different speed ratios have different gear stages and of course different lengths, the longer the length the lower the efficiency.


As the efficiency of transmitting torque varies with the number of gear stages in the gearbox, the main factors such as assembly space, required speed and torque should be considered first when selecting a motor and gearbox.


When the motor meets all these specifications, it can be initially sized and then specific details such as exit connections and output shaft shape can be considered.

About lead screw:

The lead screw used on linear hybrid stepper motor is in general trapezoidal lead screw.

For example for Tr3.5*P0.3*1N lead screw.

Tr means trapezoidal lead screw type P0.3 means lead screw’s pitch is 0.3mm 1N means it’s single start lead screw.

Lead screw lead=start number*pitch.

So for this specific lead screw, it’s 0.3mm lead.

Motor’s stepper angle of hybrid stepper motor is 1.8 degrees/step, which takes 200 steps to rotate one turn.
Step length is linear movement the motor makes, when it takes one single step.

For a 0.3mm lead screw, step length is 0.3mm/200 step=0.0015mm/step

About Hybrid Stepper Motor Selection

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.

Application


Vic-Tech | 35mm NEMA14 geared stepper motor Application:




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.
