NEMA34 Geared Stepper Motor
The NEMA34 geared stepper, having a frame size of 86x86mm, combines a precision planetary gearbox with a NEMA34 stepper motor. There are 3 standard models in this series geared motor and the maximum torque they can be up to is 82kg.cm (1139 oz-in). With a wide gear ratio range from 3:1 to 250:1, they offer output speeds ranging from 12 to 1000 rpm. The wide range of gear ratios allows the motor to provide increased torque and operate effectively at lower speeds, making it particularly suitable for applications that require precise control and substantial power.

FAQ
Q: What is the difference between spur gears and helical gears in geared stepper motors?
A: The main difference between spur gears and helical gears in geared stepper motors is the tooth orientation. Spur gears have straight, parallel teeth that mesh directly, causing more noise and vibration but providing higher torque. Helical gears have teeth at an angle, which reduces noise and vibration but can result in a lower torque output and require more axial space. Helical gears are often chosen for applications where noise and smooth operation are essential.
Q: Do geared stepper motors require a separate driver or controller?
A: Yes, geared stepper motors typically require a separate driver or controller to operate. The driver translates control signals from a microcontroller or computer into precise step commands, managing the motor's rotation. The driver sends the appropriate current to the motor windings, ensuring it moves accurately. The driver and motor work together to achieve controlled motion in applications like robotics, CNC machines, and 3D printers.
Q: Could you describe the packaging used for your motors?
A: Our motors are securely packaged in shock-absorbing foam. Each motor is placed in an individual pocket within the foam to prevent any potential damage from contact with other motors and to withstand the rigors of transportation, including intense vibrations.
Q: Are discounts available for large orders?
A: Yes, we offer discounts for large orders, and the specific discount rates also vary depending on the model. Please get in touch with our sales team for more details.
