Power Density Increases Performance

Posted by Dave Beckstoffer   Nov 06, 2018   0 Comments

Power density is the amount of power (time rate of energy transfer) generated per unit volume of the motor. The more powerful the motor in a smaller envelope, the higher the power density. Volume power density is an important consideration where space is constrained or where maximum output is needed in a fixed space. High power density enables miniaturization of applications and end devices or higher capability in current devices.

Why Efficiency Is Important

Posted by Dave Beckstoffer   Jul 17, 2018   0 Comments

Motor efficiency is the ratio between power output, which is mechanical, and power input, which is electrical.  Losses exist in all motors due to friction, heat, and materials, to name a few factors, so minimizing these losses is critical for applications that run off a battery.  The higher the efficiency of the motor, the longer the battery life during operation which results in longer time between charging.

High Speed Linear Actuators

Posted by Sandeep Cg   Mar 29, 2017   0 Comments

An in-depth discussion on high-speed linear actuators that use disc magnet motor (DMM) technology, and their uses in low-load applications such as sensor movement, positioning a laser beam, pick-and-place of electronic components, movement of XY tables, and other applications. Quiet operation and lower operating and maintenance costs make electric DMM linear actuators a viable option for these high-speed, low-load applications.

MotionCompassTM – Selecting the “right” motor for your application

Posted by Vinicius Cabrera   Jun 15, 2016   0 Comments

 

Are you an original equipment maker [OEM] looking for a specific motion control solution for your end application? Portescap caters to miniature motor requirements of a wide range of medical, diagnostic and industrial applications. This ranges from medical and surgical tools, lab automation equipment, dental drills and textile yarn guides to humanoid robots, surveillance camera systems, aircraft seat actuation, tattoo machines, and more. We help OEMs select the “right” miniature motor to power their applications. Our solutions include miniature dc and bldc motors, miniature can stack steppers and disc magnet motors as well as linear actuators with gear composite. These are usually customized to varying degrees, to suit requirements of the end application.

Since our motors are exposed to diverse operating conditions, selecting the right motor can be a daunting task. Certain applications need motors that can operate at extreme temperature ranges, whereas in some cases, OEMs are looking for motors with ability to withstand shocks and vibrations. Parameters like “length”, “diameter”, “torque”, “speed”,  “power density” etc  play an important role in motor selection. Thus, we’ve provided our clients and prospects with an online platform - MotionCompassTM, that helps them select the best-suited motor for their application.

Understanding Speed-Torque Characteristics of Miniature DC Motors (Part 3 of 3)

Posted by Sandeep Gandre   May 30, 2016   0 Comments

Read: Part I  |  Part II

[continued...]

The thermal data given in our catalogue may be indicative, and it should always be confirmed whether the heat dissipation in a given application is actually better and stable. As per the speed-torque curve in Portescap’s catalogue, there is a temporary working range in which we can overload the motor for a small time span. However we should always confirm what that time span should be, and it all really depends on motor size and design. There is a definite time span for every motor size, and this limitation comes from the coil temperature and more precisely, how fast the motor coil or winding heats up.

Miniature Disc Magnet Motors for Textile Applications

Posted by Norbert Veignat   Mar 14, 2016   0 Comments

 

In the 80’s, Portescap was mainly involved in the watch industry providing small stepper motors to be used in watches and clocks. Using rare earth magnets, we then designed the first micro motor with a multipolar structure. Such a design avoids additional pole shoes on the rotor to create fewer steps per revolution. Later, Portescap expanded its expertise to include bigger motors for industrial applications [< 100 W].

Miniature Motors for Valve Actuation

Posted by Anant Bhalerao   Jan 27, 2016   4 Comments

An expansion valve is a flow-restricting device present in a refrigeration system that causes a pressure drop of the working fluid. The valve needle remains open during steady-state of operation. The size of the opening or the position of the needle is related to pressure and temperature of the evaporator. When set and controlled properly, an expansion valve will keep the evaporator active throughout its operation.  There are two types of electric expansion valve technologies popular in the market place - pulse width modulated valves, and stepper motor driven valves.
