The tiny SQL-1.8 Squiggle motor travels as fast as 7mm/s and pushes axial loads of up to 30g - nearly 200 times its own weight of 0.16g.
New Scale Technologies has added a stronger, faster motor to its SQL Series of piezoelectric Squiggle motors, the world's smallest linear motors.
The tiny SQL-1.8 Squiggle motor travels as fast as 7mm/s and pushes axial loads of up to 30g - nearly 200 times its own weight of 0.16g.
This is 40% faster and 50% stronger than the company's slightly smaller SQL-1.5 Squiggle motor.
At 1.8 x 1.8 x 6 Mm, the SQL-1.8 is still less than half the size of competing micromotors.
New materials and thread design in the linear drive screw enable high volume automated manufacturing on the company's newly commissioned precision robotic assembly line.
They also give the SQL-1.8 a lifetime expectancy of at least 300,000 cycles, compared with 100,000 cycles for the SQL-1.5.
"Through continuous innovation, we are bringing our patented Squiggle motor technology into mass production for use in phone cameras, medical devices, electronic locks and more", says New Scale CEO David Henderson.
"Squiggle motors allow electronic product designers to achieve major performance advances in smaller and smaller products".
