EC 45 flat 70 W brushless DC outrunner motor

A 70 W version has been added to the maxon motor range. The EC 45 flat 70 W displays a flat speed/torque gradient. Flange pattern, fixation and socket are identical to the existing EC 45 flat 50 W version; the difference is that the 70 W motor delivers 38% more torque.

The device possesses good key data. It delivers a maximum continuous torque of 130 mNm at an efficiency of up to 85%, thus making it a good choice for the use in self-contained drive systems as well as in industrial automation applications.

The motor is available with Hall sensors and comes in four windings (24, 30, 36, 48 V). It can be combined with more than 54 different planetary and spur gearheads of series GP 42 C and GS 45 A. For control purposes, there is a wide variety of servocontrollers (DEC, DECS, DECV and DES) and positioning controllers (EPOS2 and EPOS2 P) available.

The flat design of the brushless DC flat motors makes them suitable for many applications. Designed as internal or external rotor motors, they are suitable when space is limited and the simple design means that production is largely automated.
