From the market leader in integrated motion control and the MDrive ® platform comes
motion technology TM
Servo and Stepper — the two motion technologies have been very prominent in the motion control in-dustry for decades. Traditionally, both systems have their advantages and disadvantages when applied to motion applications, including:
Servo technology —
Advantages
1. Capable of supplying peak torque

2. Can deliver signifi cant torque at higher speeds
3. Continuous clod loop
Disadvantages
1. Need for PID tuning
2. Error driven
3. Higher complexity
4. Higher price point
5. Servos have inherent dither -slight shaft oscillations at
position

Stepper technology —
Advantages
1. High torque at low speed
(may eliminate need for gearbox)
2. Shaft stiffness at standstill
沟通艺术3. No tuning
4. Cost effective
Disadvantages
1. Threat of loss of motor synchronization or stall
2. Must size with up to a 50% torque margin
3. Constant torque and current device
4. Excessive heating
5. Resonant zones -dependent on system to which mounted
The gap between stepper and rvo technologies.Historically, the advantages and disadvantages
of both rvo and stepper systems have drawn a rather clear line as to when one or the other is ap-plied. Most design engineers have justifi cations for a preferred motion platform. Engineers may have ud a technology in the past and developed their opinion bad on a positive or negative experience. Servo system manufacturers have tried to domi-nate the motion arena while placing dou
bts among would-be urs of anything other than rvo, and they have had a good measure of success.
Many manufacturers abandoned further product development of stepper motor bad systems for which Intelligent Motion Systems (IMS), now IMS Schneider Electric Motion USA, has benefi ted over the last 15 years. This has allowed IMS SEM to gain signifi cant market share and, through a continued commitment to stepper motor control technology, emerge as the innovation market leader with the MDrive®integrated platform of products.
With the introduction of the MDrive integrated plat-form in 2001, and since having sold over ½ million of the products worldwide, IMS SEM solidifi ed its leadership position in integrated motion control and continues to be recognized as the innovation leader in stepper motor control systems.
Today, IMS SEM continues our commitment to innovation by introducing another new patented motor control technology:
Hybrid Motion Technology™.
Servo and Stepper Technologies蜂拥而至造句
Hybrid Technology
Hybrid Motion Technology™ more than fi lls the gap between rvo and stepper motor technologies.
The bene fi ts include: • Variable current / torque • Real time control
• Optimum torque at all speeds • Stiffness as standstill • No tuning
• Cost effective
Hybrid Motion Technology™ also greatly expands the application range of stepper bad motion con
trol to include:
• Web tensioning • Clamping • Roll feeders
• Force applications – requiring torque mode • Conveyors • Rotary knife • Pick and place
– unaffected by tansient loading
What does Hybrid Motion Technology ™ mean to the design engineer?
1. A compelling alternative for demanding motion applications
2. Reduced system cost
3. Reduced complexity
IMS SEM recognized a gap between stepper and rvo technologies, and addresd this by creating a new motion control technology. This new technol-ogy delivers the bene fi ts of both rvo and stepper motor technologies, with unique capabilities and enhancements over both.
夜晚的描写Becau the industry needs a clear de fi nition and way to have deliberate discussion as to its applic
a-tion, this new technology required a name. And, being the innovation leader in stepper motor bad control systems, we believe we have the inertia within the industry to coin the term for this new category of motion control.
So we recommend this new technology be referred to generically as “hybrid”, within the context of motion control, as the best intuitive reference.So, now we have:
• Stepper • Servo
• Hybrid
And IMS SEM has trademarked our version of this new motion control category:
• Hybrid Motion Technology ™
As you can e in the fi gure below, Hybrid Motion
Technology™ not only eliminates many drawbacks of stepper and rvo systems, it introduces bene fi
ts.

For
2+ years
Hybrid Motion Technology™
has been solving demanding applications for customers.
MDrive® motor+driver with Hybrid Motion Technology™
low cost integrated solutions where brushless motion is required Environmentally friendly energy
saving
variable current control feature reduces electrical power consumption
眼下Hybrid Motion Technology™ changing the rules of motor control preventing the loss of synchronization due to transient or continued overload, extreme accel-eration or deceleration, or excessive slew speed when applied to stepper motors Hybrid Motion Technology™ is available in industry leading MDrive® motor+driver products. The integrated motion systems solve many rvo applications with a compact, low cost stepper solution.
