EmailECH Series Brushless Coreless Motor Overview
ECH series DC brushless coreless motors adopt electronic commutation, which senses the position of permanent magnets by Hall elements and then switches the current direction in the electronic circuit, thus changing the magnetic force.
The advantage of ECH series motors is that it eliminates the loss of brushes and the interference of electric spark to electronic equipment, prolonging service life to tens of thousands of hours.
These motors offer higher speed and torque and lower noise and vibration for smooth operation and more precise control.
Product Features
This motor is free of the brush and the core while it can offer high-speed, high-torque, and low-noise and low-vibration operation by even more precise control. And the compact motor provides higher efficiency and power density.High-speed/torque
Low eddy current losses in the core and the close arrangement of the windings for high-speed and hightorque operation.
Low-noise/vibration
No cogging effect on the motor core for stable motor performance at different speeds.
Rapid response
Low motor rotor inertia, mechanical time constant less than 28ms, 10ms for certain products (100ms or more for general motors with cores).
High power density
Less weight and volume by 1/3-1/2 compared to general motors with cores.
