The right servo motor is significantly important to the performance & efficiency of a sewing machine, and the HM-750L is an ideal motor for a multitude of different types and styles of sewing machines. The HM-750L is the result of over 4 years of research and development into producing high power, high torque sewing machine servo motors. The Kinedyne HM-750L is the first powerful servo motor made specifically for medium to heavy duty leather sewing machine. Compared to other foreign made energy saving servo motors, the HM-750L offers a true 750 Watts of output power, and an awesome 7.9 Nm of bone-crushing torque. In the world of industrial sewing machine servo motors, the TRUE horsepower, wattage, and torque of servo motors are often overstated, and these true ratings are often much lower than the advertised specifications. The HM-750L is much more powerful than other brands of power saving motors, and can work on any medium and heavy duty sewing machines without any difficulty. With speeds from 300-3000 RPM, the HM-750L is an excellent general purpose motor for use where extremely slow speed is not needed. The durability and reliability of the Kinedyne HM-750L heavy duty servo motor is far better than other foreign made brushless servo motors.

For production manufacturers, “acceptable performance” is not enough!! They usually need high efficiency heavy duty industrial sewing machines with automatic functions, such as a pneumatic/automatic foot lift & reverse stitch, puller, pneumatic seam guide, needle cooler etc. The need for these added functions why the HM-750T was developed.
The HM-750T features an advanced synchronizer (needle positioning sensor) which will allow the operator to stop the needle in up & down positions independently with precision. This level of accuracy and precision is not found on other competitor’s servo motors. The needle positioner is ideal for turning corners while sewing or any other applications that require UP and DOWN needle positioning. "How many times a day do you have to remove your hand from your work, turn the hand wheel to raise or lower the needle, then remove the material?” The Kinedyne synchronizer is an indispensable time saving tool for high production manufacturers.
The major difference between the Kinedyne HM-750L and the HM-750T is that the 750T can support automatic functions such as auto presser foot lifter, auto reverse, needle cooler, and auto puller mechanism..

In the realm of craftsmanship, where every stitch is a testament to dedication and precision, having the right machine can make all the difference. When start to supply our 797 leather sewing machine to a major leather hobby retailer in the USA, we were faced with the challenge of how to develop a new servo motor that could make the sewing machine far more manageable. The need for precise, stitch by stitch slow and accurate sewing speed was our goal. Our engineering team worked extensively on the problem and created a high power servo motor that did not lose HP and torque when set to the slowest possible speed., and finally succeeded in developing Kinedyne HM-750SL slow speed high HP and torque servo motor. A significant advantage of this servo motor, especially appreciated by leather crafters & saddlers, is its ability to sew stitch after stitch at extremely slow speed, but at very high HP and torque. This creates an awe-inspiring motor design which allows unimagined low speed control, while while providing tremendous punching power at very low RPM. The minimum motor speed can be as low as 50 RPM, and allows you to take complete control of the sewing process, thus enabling the operator stitch by stitch sewing control and precision -- creating the most precise stitches possible with any sewing machine.
The HM-750SL is a huge step above other foreign made servo motors, and performs far better than these motors in every aspect.
The HM750-SL features a near silent operational noise level as well. It allows for a very pleasant sewing environment without the noise of a traditional servo or clutch motor in the background.

While HM-750SL can easily drive most medium and heavy duty leather stitchers and is perfect for the use of hobbyists and small production shops, large scale manufacturers whom are using the sewing machine motor for hours and hours per day on multiple shifts may need a little more assurance and protection. High heat build up from 10-12 continuous hours of operation every day may affect the lifespan of the motor, so we recommend our HM-750SH for such high demand applications. We improved the computer control board with an overheat controller which keeps the motherboard and interior control box components running cool to prevent overheating. In addition, we equipped this motor with with ports and firmware to drive an automatic presser foot lifter, needle cooler and automatic reverse. Under advisement by some of our experienced dealers from around the world,we created some user-friendly features, like a Soft Start function, “Jog-Dial”, Half-Stitch etc. All of these features make the HM-750SH low speed powerful servo motor one of the most complete and sophisticated motors in the market today!!
Many leatherworkers still use a speed reducer unit in addition to a servo motor to provide for the best control and punching power for adverse situations. The addition of a speed reducer can make the handwheel on the sewing machine very hard to turn, and it presents another area of potential failure and maintenance as it requires the use of an additional belt and pulley system. With the HM-750SH servo motor, the speed reducer pulley system can eliminated in many sewing applications.
In terms of performance and reliability, the HM-750SH is the best leather sewing servo motor on the market today!!

Kinedyne HM-750SH can drive most heavy duty sewing machines without any difficulty. However we wanted to ensure extra reliability and power with a more powerful servo motor for extreme operating conditions. For example, CB-4500 extra heavy duty leather sewing machine, 366-76-12-HM robust long arm zigzag sewing machine, 733 CS extreme heavy duty sewing machine, and 728-30 long arm twin needle heavy duty sewing machine are great machines that can use this motor. Long arm , heavy duty leather, and double needle machines require extremely high torque. That's why we developed the HM-1000SH super powerful sewing servo motor. Usually these heavy duty and long arm sewing machines only utilize less than 70% of this motor's capacity, so it can last for an extremely long time and offer excellent reliability while powering these machines.
All Kinedyne servo motors can save 60-80% electricity, so usually the cost of these servo motors can be recovered within 2-3 years by saving money on electricity alone. However the advantage of the time savings and labor savings cost will make the actual return on investment much faster.

In today's fast-paced world, the demand for intelligent automation is growing very quickly. We are frequently asked about the multifunctionality of servo motors. HM-1500G intelligent servo motor offers comprehensive control for heavy duty sewing machines equipped with foot lift, puller, trimmer, thread tension release, back-tack, and many more custom made special sewing machine applications.... This programmable strong servomotor incorporates an integrated incremental encoder, and delivers outstanding torque & precision control for most heavy duty industrial sewing machines. This 1500 Watt model offers over 2 horse power which can unquestionably drive the most heavy duty sewing machine with ease.
This robust & compact servo motor features an output for a 24 Volt DC current LED sewing lamp that will provide bright & clear lighting for your projects, yet remain compliant with all safety regulations for LED lighting. Most motors only have ports for a 5 Volt DC light, so this motor can run a much brighter LED light when compared to other servo motors. In addition, this motor is completely programmable allowing a multitude of automatic functions that can be utilized with this motor, and allow the operator to select which functions they want to use with each sewing machine and the demands of the particular sewing job.
The HM-1500G is the ultimate in heavy duty powerful electric programmable servo motors. It truly stands out from the rest as an excellent replacement for expensive models like Ho Hsing i90 and Efka DC1550 at a lower cost.
