Features and Benefits
Thin & Compact
3709 Series motors feature flat/puck-shaped design and range from 14 to 22 mm in thickness. Making the motor a perfect fit for compact and portable devices, where size or weight is essential.
How Did We Do It?
The motors feature a unique end-cap design that incorporates the bearings, and the entire unit is sealed and laser welded for strength and longevity of the product. Being resourceful allows us to create a very compact motor.
3709 Series motors are capable of producing up to 16 oz-in of holding torque. This is quite astounding for such a small motor.
Multiple Mounting Options
Motors are offered in variety of standard mounting options in NEMA 17 offsets. Available hole patterns include Thru hole DO 0.13, #4-40 UNC and M3 x 0.5. Additionally, Lin Engineering can place the motor in almost any customer supplied/designed housing imaginable. Multiple Shaft options are also available.
Part of Our Signature Series
0.9 Degree step angle ensures smooth motion, while Signature Series further reduces resonance
for higher accuracy. The Signature Series was developed to help reduce system resonance and provide overall smooth motion. Depending on Application, using motors with the Signature Series technology may result in up to 40% less resonance being produced.
Depending on application Signature Series Stepper Motor user can expect anywhere from 10-40% less resonance being produced.
The design creates double the detent positions (un-energized cogging) in the standard stepper. When doubled, the amount of torque or drag that each detent position has is decreased by half, thus creating a smoother motor during operation
Customizations & Optimizations
Lin Engineering can ensure that your hybrid stepper motor is optimized to deliver the required performance for your specific application, whether it’s increasing torque at a specific speed range, reducing noise or vibration, or optimizing for minimal power consumption, or making specific modification to ensure proper and native fit within your assembly.
Customization Services Include:
- Optimized Winding
- Multiple Shaft Options
- Customized Leads & Connectors
- Customized Housings & Mountings
- Bearings & Lubricants
