The slim design of the EC 90 flat motor is now equipped with a MILE encoder. According to the manufacturer, MILE (Maxon’s Inductive Little Encoder) is the world’s smallest inductive rotary encoder. Its operating principle is based on the detection of high-frequency inductivity, which generates eddy current in an electrically conducting target. The advantage of a high-frequency inductive method of measurement includes high speed, high robustness towards dust or oil vapor and insensitivity against interference pulses such as PWM controllers or motor magnets. Resolutions are up to 3200 impulses per turn, with a nominal torque of 517 mNm.
