Long life for ironless rotor motors

New from Electro Mechanical Systems are two 26mm-diameter neodymium magnet ironless rotor DC motors from System Faulhaber along with complementary 26 and 44mm planetary gearheads.

New from Electro Mechanical Systems are two 26mm-diameter neodymium magnet ironless rotor DC motors from System Faulhaber along with complementary 26 and 44mm planetary gearheads.

Designated the 2642 - CR and the 2657 - CR, the new motors, like other models in the Faulhaber high-performance neodymium magnet ironless rotor DC motor range, are aimed at long life, compact drive applications where size, power-to-weight, power-to-volume and high efficiency are all critical.

The 26mm planetary gearhead is designated the 26/1 while the 44mm version is designated the 44/1.

The 2642 motor has a nominal length of 42mm and delivers up to 23W.

The 2657 is nominally 57mm long and can deliver up to 44.5W.

Both models have graphite brushes, copper commutators and pre-loaded ball bearings to give an operating life of up to 5kh at catalogue recommended values.

Torque ratings are up to 4.5Nm on the 26/1 gearhead and 20Nm on the 44/1 gearhead.

The operating life of the 26/1 gearhead may be extended by specifying optional all-steel gears and heavy duty lubrication, a feature that comes as standard on the 44/1 model gearhead.

The new motors can be mated to a wide range of encoders, tachogenerators and other gearheads from the Faulhaber range.
