The Maxon EC-i 40 is a brushless DC motor in the EC-i (EC internal rotor) series with a 40 mm diameter. It delivers continuous output power up to 70 W in an extremely compact form. Maxon ironless winding technology ensures ultra-low friction and long lifespan.
Widely used in surgical robots, exoskeletons, prosthetic limbs, and humanoid robots. Available with various supply voltages (18–48 V) and as a complete drive module with Maxon encoders and planetary gearheads.
BLDC Motor · serves as: Joint Actuation, Motor Control.
Which group EC-i 40 belongs to and how it is built
The BLDC (Brushless DC) motor is widely used in robotics due to its high efficiency, long service life, low mechanical wear, and the ability to precisely control speed and torque. BLDC motors are found in robot joints, grippers, dexterous hands, cooling fans, and mobile platforms. Combined with an appropriate controller and encoder, they form the foundation of modern electric drive systems.
