Portescap in Motion

Seeing beyond what's in the catalogue

Seeing beyond what's in the catalogue: Why it's important to get in touch with Portescap

Finding the right motor can be a challenge. Often a product catalog only lists a selection of available motors and coils, so the ideal solution can't be found by browsing through available standard options. Some motor manufacturers offer customizations, which require time and money to be invested and might not always be an option depending on the size of the project.

Portescap's Innovative Dual Motion Can Stack Actuator Solution

Rotary and Linear Motion in One Compact Solution

Some applications require rotary motion, such as ventilators. Others require linear motion, such as medical pipettes or syringes. When it comes to combining a rotary and a linear motion in the same application, designers often need to integrate 2 motorized solutions so they can control both degrees of freedom (rotation and linear) at the same time.

Driving DC Brushed Motors

To control a DC motor, a variable, and controlled power supply is needed. There are three types of methods that can be used:         

    • Voltage-controlled linear supply
    • Current linear supply
    •  PWM (Pulse Width Modulation)

Brushless DC Motors Let You Avoid Having To Compromise On Performance For Low Voltage Battery Powered Tools

Posted by Guillaume Mougin   Aug 11, 2020   0 Comments

Today’s most challenging battery-operated tools require power, speed, and efficiency within the most ergonomic package. Studies have proven that users prefer a smaller and lighter tool with a high level of performance. The ergonomics needs have tremendously increased in the last few years to highlight operator comfort and efficiency while using battery-powered tools.  

There are multiple ways to lighten the tool. For example, we recognize the battery of the tool as one of the heaviest components, therefore the trend is to reduce the battery size. Lowering the battery size will affect the number of cells and thus the voltage: The smaller the battery, the lower voltage.

Industrial power tools support the increase in productivity while remaining versatile. We achieve productivity gains thanks to faster working cycles, so the tool should deliver higher speeds. We derive versatility from an increased torque capacity.

Why An Encoder?

Posted by Chris Schaefer   Jun 16, 2020   1 Comments

Encoders provide feedback for accurate control of speed and positioning. The rotor angular position is given through two square waves 90 degrees shifted and an optional index pulse occurring once a revolution. There are multiple technologies to get these results.

Selecting the Optimum Motion Technology for your Application: Duty Cycle

Posted by Dave Beckstoffer   Dec 04, 2019   0 Comments

The next factor to review is the duty cycle for the motion solution in the application.  The duty cycle is defined as the ratio of the time the motor operates divided by the amount of total time for the cycle.  Typically, the motor does not run continuously but rather operates for a period (on-time) and then rests for a period (off-time).  The duty cycle affects the selection of the optimum motion solution, so it is important to understand the details and factors to consider.

A Balancing Act

Posted by Christina Heston and Nate Schutte   May 16, 2019   1 Comments

What is rotor balancing?

Rotor balancing is the process of bringing the mass center axis of a rotor in line with the rotor’s shaft axis, within certain industry balance standards. A rotor, balanced or unbalanced, wants to revolve around its mass center axis. The balancing process brings these two axes together. As illustrated below, when the mass that causes the imbalance is removed, the two axes merge.
