10mm diameter stepper motors – our smallest yet!
<p>  Nippon Pulse’s smallest stepper motor to date is the 10mm diameter PFC10. It is a bipolar, two-phase tin-can stepper, and is well-suited for design into applications such as valve control and fluid dispensing, gaming machines and medical devices. The standard PFC10 motor has built-in connectors to ease system integration.</p>

Controller chips offer a variety of origin return sequences to meet application requirements
<p>  Origin return (or built-in homing) allows the controller to move the motor back to its initial, or starting, position. Every Nippon Pulse controller chip, in each of the four series, has multiple origin return sequences available, though the specific types of return modes available are dependent on the model.</p>

Extreme Customization, Well-Maintained Tooling, and Accuracy

An OEM small-batch manufacturing customer came to Nippon Pulse because their current supplier was producing motors that had a very high failure rate for their application. The supplier’s motors had worked fine for previous generations of their system, but the new generation required an accuracy from the motor that 50 percent of the delivered motors could not meet. The motor was spec’d to have sufficient resolution for the application, but was unable to deliver the accuracy. This customer contacted us and requested a sample to evaluate, which – when tested – was well within their resolution and accuracy requirements.

Linear Shaft Motors in Parallel Applications

Nippon Pulse's Linear Shaft Motor has been successfully used in parallel motor applications. Parallel applications are ones in which there are two or more Linear Shaft Motors in a parallel arrangement. The advantage that the Nippon Pulse LSMs have over other systems is the capability to run all parallel motors with only one amplifier and one encoder.

Linear Shaft Motor Sizing
<p>  One of the most straightforward tasks in the design of a linear motion system is to specify a motor and drive combination that can provide the force, speed and acceleration that is required by the mechanical design.</p>

Linear Shaft Motor 50 Percent More Efficient than Coreless Linear Servos
<p>  Linear motors have gained a name for themselves as being a high-precision and power-efficient alternative to conventional rotary-to-linear transmission systems. How is this possible?  Well, let’s look at the Ball Screw, which also can be considered, in its own right, a high precision rotary-to-linear transmission system.  The Ball Screw is typically only 90 percent efficient<a href=

Linear motors have gained a name for themselves as being a high-precision and power-efficient alternative to conventional rotary-to-linear transmission systems. How is this possible?  Well, let’s look at the Ball Screw, which also can be considered, in its own right, a high precision rotary-to-linear transmission system.  The Ball Screw is typically only 90 percent efficient[1].  When we add the efficiency of the servo motor (range from 75 to 80 percent[2]) and losses that will be introduced by the coupling (and if using a gear box), it is possible that only 55 percent of the power we are supplying is going towards work.  When we compare the typical linear motor, where the motor is driving the load linearly, we can quickly see why the linear motor has gained a name as being more power-efficient.

An Independent Review of the Energy Efficiency of the Linear Shaft Motor
<p>  In 2010, Nippon Pulse took its Linear Shaft Motor comparison demo unit to the University of Virginia to receive an independent evaluation. Nippon Pulse wanted to verify the claim that the Linear Shaft Motor is 50 percent more energy-efficient than a comparable U-shaped linear motor.</p>

Linear Shaft Motors in Parallel

With the Linear Shaft Motor, you have the ability to drive two motors in parallel using only one encoder and one amplifier. All other systems require two drives, two controllers and two encoders, connected together. How is the Linear Shaft Motor able to overcome these issues?
