Allied Motion Technologies expands its range of coreless DC motors with the addition of the new DynaMax 25 series motors. The new 25 mm diameter DynaMax 25 coreless motors employ an innovative high power density copper foil rotor technology instead of a conventional copper wire armature winding.

This new rotor technology combined with 4-pole rare-earth NdFeB magnets maximises the DynaMax’s performance. Starting torque is 400 mNm, allowing this motor to claim the best-in-class position for torque and power production in its size class. The low inertia realized with this new rotor technology combined with the high starting torque results in a rapid rotor acceleration response of just 4 msec. These features make the DynaMax 25 ideal for rapid start-stop applications, as found in hand tools and actuators, as well as positioning systems in high precision, high throughput equipment such as semiconductor test and packaging equipment and electronics assembly equipment.

For those applications needing lower speeds and higher torque the DynaMax 25 is also available fitted with a planetary gearbox. For regulated speed or positioning systems a twochannel optical encoder with a resolution of up to 2000 ppr is optionally available.
