Flat motor: small but tough

The EC 9.2 Flat motor addresses the problem of providing adequate power in small-sized applications. Measuring just 10mm in diameter, including a protective outer cover, the motor provides a high nominal torque of 0.83 mNm, with a stall torque of up to 1.29 mNm. The EC 9.2s unusually small size is enabled by its external rotor. This contains a ring-shaped 8-pole Neodymium magnet, which rotates around a three-phase winding system to create a rare level of output for its size.

This innovative design means that even with its protective covering, the EC 9.2 Flat is considerably smaller than other motors with similar performance.

maxon senior sales engineer Paul Williams commented: The EC 9.2 Flat takes compact engineering to a new level. For its size, the amount of torque is phenomenal.

Crucially, the motors production adheres to the ISO 13485 medical technology standard. This means the EC 9.2 Flat is assured for use in medical applications where instruments require the highest power possible in very limited space.
The motor is also ideal for industrial applications where size is an issue for example, in pumps for miniature fuel cells.
The EC 9.2 Flat comes available with or without Hall effect sensors and, like all maxon products, is designed to be modular, rendering the motor instantly compatible with many thousands of gearhead and controller combinations.

Mr Williams added: The EC 9.2 Flat is proof that great things really do come in small packages!
