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.

The Additional Benefits of Partnership

Posted by Dave Beckstoffer   Aug 02, 2018   0 Comments

As discussed in our collaboration post, early engagement leads to customized motors that are optimized for your application, but additional benefits can be realized utilizing Portescap’s Engineering expertise. Discussions will focus on the motor solution but routinely extend to the sub-assembly where the motor will reside. These early meetings can resolve challenges an Engineer may face around material selection and additional mechanical components.

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.

Portescap Introduces New P532 Motor Series for Best-in-class Power Rate and Acceleration

Posted by Dave Beckstoffer   Dec 21, 2015   1 Comments

Portescap has recently introduced the P532 Series Disc Magnet Step Motor with encoder to deliver best-in-class motor acceleration and power rate and thus outperform the standard Brushless DC motor in a wide range of applications.

Stepper motors typically run at 2,000 RPM or less in an open loop, while brushless motors that can run at much higher speeds are typically used in closed loop applications. In the last few years, trend is to use a stepper motor in closed loop with a torque higher than a brushless motor system, because of its higher pole count. What we are typically looking at is the middle range of revolutions per minute [RPM] as a sweet spot for disc magnet motors. The sweet spot opens up in applications in the few thousand RPM range, where a closed loop disc magnet motor system can be more cost-effective than a brushless solution.
