Well, it becomes clear with the clear path for a few different reasons.
First is the 90 day trial period. Yes I have already tried that and had to return one motor. It was not strong enough to do the job I needed. So question for you George, are you offering the same return policy on your motor kits? I was able to return motor and purchase another without talking to a single person. Did it on line. I did pay for the second motor as I wanted it quickly. The new motor showed up and when they received the other motor I got the credit quickly. I know I did not over buy for my machine.
Second, the resolution of the enhanced encoder is 6,400 pulse count and steps per rotation. This can be changed up or down in software but the motor's smallest step is .06 degrees. This comes in handy for a faster screw. It does cause an issue, if you don't know how to handle it, with mach 3 and the speed limits you hit with the output frequency.
Third, the clearpath has a usb connector on the back of the motor for tuning, diagnostics, and other useful information. Here I believe it maybe possible that the leashine does as well. Please elaborate here George as I am curious.
Fourth, the feedback signal from the motor can be used to halt Mach 3 when there is an issue or a crash. Again I would assume that the leashine are capable of this as well.
Fifth, and this is important, easy integration for any setup that was designed for an actual stepper motor. Since we have paved the way, it should be easier for others to follow.
Come on in the water warm.
Jim.
Awesome warm water , just what i have been waiting for . Can you shed some light on what the gain are using Clearpath.
Don't tell me, tell the people looking for motor kits? i don't know why you telling stuff.
Just tell benefits of BLDC motor
Tell me how it can have more torque then a stepper without any belt reduction.
I am truly amazed by the fact that you don't need reduction and have motor torque than 1133oz stepper for low end . Most cutting is 150 to 300 ipm in heavy cutting.Lots of times less.
Im just in trying to grip the info on this.
Due to combining the features of both brushless servo drives and stepper drives, Leadshine easy servo drives are suitable for both upgrading conventional stepper systems, and replacing brushless servo systems.
Since the ES easy servo system is a stepper motor based system, so it has the advantages of high stiffness at standstill, high torque at starting and low speed, eliminating gear box. The ES adopts sophisticated control algorithms to take advantage of high-torque capability, providing direct-drive of high inertia loads such as flywheels and belt drives. These load inertials may be as large as 100 times the motor inertia while still providing smooth positioning control. Conventional servo systems typically cannot exceed a 10:1 inertial mismatch.
While conventional stepper systems are typically adopted for applicatons of 1,000 RPM or below, Leadshine easy servo drives can easily power control systems at least to 2,000 RPM (even higher) with much fast acceleration, much lower heating , higher torque, no loss of steps, smoother motor movement. In comparison to brushless servo drives, Leadshine easy servo drives can power control systems with much high starting & low-speed torque, no hunting, no overshooting, zero setting time, lower costs, and almost "No Tuning".
Leadshine easy servo drives and matching easy servo motors have been successfully implemented by hundred of OEM clients around the world in tens of industries, such as CNC machineries(routers, laser cutters, milling machines, engravers), medical, robotics, semiconductors, electronics, packaging, lab automation ...
By adopting high resolution encoders, Leadshine easy servo drives apply servo controls on stepper motors, the same mechanism in those expensive brushless servo drives. In a Leadshine easy servo system, shaft position of the stepper motor is fed back to the servo drive in real time. The easy servo drive can then close the position loop and correct any position errors to eliminate loss of steps commonly seen in open-loop stepper motors.
Leadshine easy servo drives inherit favored features of both open loop stepper and brushless servo drives. When combined with easy servo motors (stepper motors with encoders), Leadshine easy servo systems solve the fatal problem “loss of steps” of open loop step systems. Other drawbacks of open loop stepper systems like high motor & drive heating and noise are also significantly improved. At fractional cost of expensive brushless servo systems, Leadshine easy servo system can upgrade your stepper systems to servo like performance with extra low motor heating, quick response & acceleration, and no torque reservation. In comparison to brushless servo systems, Leadshine easy servo systems outperform in much lower cost, no hunting, no overshooting, almost zero settling time, no tuning for most applications. Click the “Main features” tab to see illustration, or click here to read more about what is Leadshine easy servo system.
Currently, Leadshine offers two series of easy servo drives. The ES-D series easy servo drives which take input voltage of 20-80 DC or max 80AC input to power motors from NEMA 23 to 34. Our ES-DH series easy servo drives can take direct 110 / 120 or 220 / 230 AC input to get rid of power supplies and power motors up to NEMA 42 easy servo motors to provide huge torque for big machines.
Due to closed loop control and adoption of advanced control algorithm, the ES series easy systems can always implement 100% torque of the motor, and do not need the huge 50% torque reservation in normal open-loop stepper systems. This feature significantly improves system high speed performance. While open-loop stepper systems are typically adopted in applications under 1,000 rpm, the ES series easy servo systems are ideal for many applications up to 2,000 RPM, sometimes even for 3,000 RPM!
For the case of conventional servo motor systems, there is a considerable delay between the commanding input signals and the resultant motion because of the constant monitor of the current position, necessitating a waiting time until it settles, called settle time.
Since the ES easy servo is a stepper motor based system, it operates in synchronism with command pulses and has no hunting problem. When it stops, its position is completely stable and does not fluctuate. It is a great feature of the ES when rapid motions with a short distance are required and it is ideal for applications such as bonding and vision systems in which hunting would be a problem.
Since the ES easy servo system is a stepper motor based system, so it has the advantages of high stiffness at standstill, high torque at starting and low speed, eliminating gear box.

These load inertials may be as large as 100 times the motor inertia while still providing smooth positioning control. Conventional servo systems typically cannot exceed a 10:1 inertial mismatch.
Unlike a servo system which usually needs the engineer to spend a long time to learn how to use tuning tools and tune the gains for a satisfying performance, the ES series easy servo is ready for operation within a very short period of time. Set the microstep resolution and operating current, then the system is ready and offers high performance approaching to a fine tuned servo. Save time and save cost.
