Electronic commutation supersedes brushed motors

Electronic commutation supersedes brushed motorsBrushless, electronically commutated motors are impressive because of their exceptionally long service life. The commutation electronics are integrated in the new EC-max 16 two-wire motor, which is only 16mm in diameter, 33.5mm long and has a nominal output of 5W. The reduction to two connection wires allows brushed motors to be replaced directly.

The new EC-max 2-wire motor from maxon Motor continues the tried-and-trusted philosophy behind the company's EC-max motors. The ironless winding of System Maxon offers important physical advantages: the motor turns cog-free and is highly efficient.

A stainless steel motor housing, when combined with the metal flanges, provides a high degree of temperature stability, good heat dissipation and excellent shielding against electrical fields. Highly automated production processes mean that the motors have an excellent price/performance ratio.

The integrated electronics allow direct control with an operating voltage of 5-15V; the motor turns in proportion to the applied voltage with the relevant speed in a given direction. The electronics have inbuilt circuits to protect the motor against polarity reversal, overheating, axle blocking and under-voltage.

With a nominal output of 5W, the motor generates continuous torque of up to 3.4mNm. A 16mm diameter planetary gearhead can be added to increase torque up to a maximum of 0.3Nm. The motor can be used in any application where a long service life but simple/compact controls are required in the same size product - such as handheld tools or space-saving automation systems.
