30mm motor with 230g load

Video: 30mm diameter motor (100 sequences)

Posted · Add Comment

We recently made the following test setup for one of our customers who required a ‘loaded’ motor to perform a specific rotational sequence. The motor used for the test is our 30mm PCBMotor w/100-Line Encoder  – modified with a 400-line encoder. The test result was that the 30mm diameter motor with a load of 230g easily […]

New technology for gauges & meters Do you have a meter, gauge, instrument board or cluster application? Are size, space, weight and thickness important issues to your final product? The video below shows how we use our PCBMotor platform to produce motors for a wide range of guage/meter applications within the automotive, marine and aviation industries. […]

What is micropulsing?

Posted · Add Comment

Micropulsing is a technique that makes it possible to rotate the motor in extremely small increments. Power is applied to the motor as very short pulses. Using an unloaded rotor, increments as small as 1/2,500,000 of a revolution are possible. Please note: By nature these increments are not well-defined step sizes like those based on […]

What’s the maximum resolution of a PCBMotor?

Posted · Add Comment

The rotors on the High Resolution Twin Motor Kit are made of PCB and the code wheel is implemented in the copper layer with 200 lines/revolution. By triggering on both leading and trailing edge of the light pulses, resolution can be increased to 400 and by using both channels in the position sensor’s edges resolution […]

What does a positioning system look like?

Posted · Add Comment

The basic elements are a: 1. Code wheel on the rotor. The rotors on our demo PCBMotors are made from standard PCB material – the code wheel pattern is an etched Cu-layer. 2. Optical reflective switch that sends light towards the code wheel and senses reflected light pulses. The demo kits use the reflective optical switch […]

Do I need a positioning system?

Posted · Add Comment

If you want to rotate the motor to a specified position the answer is yes, you do. A positioning system is needed to keep track of position and turn the power off when it’s in position. Such a system is implemented on our High Resolution Twin Motor Kit. If you’re not interested in the exact […]

Is power required to hold the motor in position?

Posted · Add Comment

No, the rotors are preloaded by springs pressing them against the piezo elements. This results in a holding torque whether the power is on or off. The holding torque is about 2-3x the stall torque. Being able to turn motor power off when not rotating can, in some applications, prove to be a very important […]
