Allied Motion Technologies adds to its range of coreless DC motors
with the DynaMax 25 series motors that employ new rotor technology for higher
performance. The new 25 mm diameter DynaMax 25 coreless motors use an
innovative copper foil rotor technology instead of a conventional wound copper
wire armature, resulting in significantly higher power density. This new rotor technology
combined with 4-pole rare-earth NdFeB magnets enables the DynaMax to achieve a
stall torque of 400 mNm and 28 watts of rated power output. The low inertia
realized with the coreless design, combined with the high starting torque,
results in a rapid 4 msec mechanical time constant.
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 as found in
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 an optional planetary
gearbox. For regulated speed or positioning systems a two channel optical
encoder with a resolution of up to 2000 ppr is also optionally available.
