Features of prosteppers’ stepping motor

Accurate Position Control

The angular displacement of the stepping motor can be precisely controlled by the number of electric pulses. Angle accuracy can be controlled within ±0.09゜without any feedback devices.

Forward/Reverse Rotation, Pause and Hold

The forward/reverse rotation of the stepper motor can be controlled by the input sequence of the controlled electric pulses.

In case of a stepper motor lock (the motor winding is energized, there is no external electric pulse command), the stepper motor can still maintain a certain torgue output.

Longer life

Stepper motor is a mechanical structure, which does not need to be commutated by brush and Hall sensor, thus reducing the probability of failure and increasing the motor life. Stepping motor life usually determined by the life of the bearing.

Basis structure:

• Screw
• Front Endbell
• Bearing
• Shaft
• Spacer
• Rotor Laminations
• Magnet
• Spacer
• Bearing
• Insulator
• Stator Laminations
• Insulator
• Spring Washer
• Rear Endbell

Quality Control Process:

1. Incoming inspection: The inspection shall be conducted according to the Requirements of the Incoming Inspection Specification or the product drawing

2. Monitoring and measurement of production process (self-inspection - inspection - batch production)

3. Final inspection and test

4. All inspectors must be trained and then put on duty

5. Nonconforming products shall be executed in accordance with Nonconforming Product Control Procedures

What we can do for you?

Q: How to select a suitable motor?
A:If you have motor pictures or drawings to show us, or you have detailed specs like voltage, speed, torque, motor size, working mode of the motor, needed lifetime and noise level etc, please do not hesitate to let us know, then we can recommend suitable motor per your request accordingly.

Q: Do you have a customized service for your standard motors?
A: Yes, we can customize per your request for the voltage, speed, torque and shaft size/shape. If you need additional wires/cables soldered on the terminal or need to add connectors, or capacitors or EMC we can make it too.

Q: Do you have an individual design service for motors?
A: Yes, we would like to design motors individually for our customers, but it may need some mould charge and design charge.

Q: Can I have samples for testing first?
A: Yes, definitely you can. After confirmed the needed motor specs, we will quote and provide a proforma invoice for samples, once we get the payment, we will get a PASS from our account department to proceed samples accordingly.

Q: How do you make sure motor quality?
A: We have our own inspection procedures: for incoming materials, we have signed sample and drawing to make sure qualified incoming materials; for the production process, we have tour inspection in the process and final inspection to make sure qualified products before shipping.

Q: What's your lead time?
A: Generally speaking, our regular standard product will need 25-30days, a bit longer for customized products. But we are very flexible on the lead time, it will depend on the specific orders

Q: What's your payment term?
A: For all our new customers, we will need a 40% deposit, 60% paid before shipment.

Q: When will you reply after got my inquiries?
