 DC Coreless Motors Reduce TCO and Weight of Solar Panel Cleaning Robots

Solar panels are growing in popularity as effective choices for large solar farms generating renewable energy. They do require regular maintenance and cleaning to ensure efficient use and long life. Currently solar power cleaning units (SPCRs) use large, heavy DC motors that weigh upwards of 1kg+ that make these robots cumbersome, inefficient and difficult to maintain.

Experimental Approach For Solving Side Band Noise of Miniature Planetary Gearbox

Vibration and noise spectra from miniature planetary transmissions commonly exhibit components at distinct frequencies around the gear mesh (tooth passing) frequency and its higher harmonics, called modulation sidebands. They constitute a significant portion of the vibration and noise generated by the transmission. Sidebands have influence on noise quality measures as well as having great potential to provide valuable clues regarding gear tooth combinations, phasing of planets, manufacturing errors like eccentricity, run out present in the gear set, planet pin position error, etc.

Bipolar Drives and Unipolar Drives for Stepper Motors: A Comparison

Bipolar Drives and Unipolar Drives for Stepper Motors: A Comparison

 A stepper motor is a type of brushless DC motor composed of connected coils — called “phases.” These electromechanical devices are generally driven in open loop without a feedback sensor, with current applied on the phases without knowing the rotor position. The rotor moves into alignment by means of the stator’s magnetic flux, generated by the current flowing in the phases. At each pulse, the current can be supplied to the next phase, allowing incremental rotational movements, or steps. There are two methods to supply current in the coil: bipolar and unipolar. This blog post will compare bipolar and unipolar motors.

How Encoders Provide Motor Speed and Position Control 

In many mechanical systems, precise motion hinges upon effective monitoring and control of the motor. Encoders make motion control possible by sensing the motor’s speed and position and sending feedback signals to control components. Two square waves, or channels, shifted 90 electrical degrees from each other, along with an optional index pulse that occurs once per revolution, encode the angular position data.

Stepper Motors for Medical Applications

Posted by Krishna Kumar   Aug 27, 2021   0 Comments

Stepper Motors Provide the Dynamic Performance Your Medical Application Requires

A stepper motor is an electromechanical device that converts electrical pulses into discrete mechanical movements and therefore can be operated directly from a pulse train generator or a microprocessor. Stepper motors can work in an open loop, the controller used to drive the motor can keep track of the number of steps executed and knows the mechanical position of the shaft. Stepper geared motor have very fine resolutions (< 0.1 degrees) allowing precise metering for pump applications and maintain a position without current because of their inherent detent torque. Excellent dynamic characteristics allow quick starts and stops.

Motor Selection Tips: Understanding Thermal Parameters of DC Coreless Motors
With the help of simple thermal modeling

When trying to understand the phenomenon of heating of coreless dc motors, its helpful to express it as a simple thermal model and to draw an analogy with an electrical system. Looking at Fig. 1, you can see the power dissipated (heat) is the difference between electrical input power and the mechanical power (speed & torque) generated by motor shaft. With this basic understanding , let’s next examine the thermal model of a DC coreless motor.

Convert Rotary Motion Into Linear Motion With These Options

Posted by Clemence Muron   May 11, 2021   0 Comments

When it comes to motion for handheld and miniature medical device designs, a standard electrical mini motor may seem like a good starting point. But while a miniature motor generates rotary movement, applications like medical pipettes or syringes, and mesotherapy devices often move loads linearly instead of rotationally. For these medical tools as well as some industrial devices, engineers must develop their own system to translate rotary motion into linear motion. Here are some of the basics to understand when considering your linear motion options.
