Allied Motion (www.alliedmotion.com) has announced its newest range of coreless motors that will bring best in class power density and torque to size ratio, including a high acceleration performance.
The DynaMax 25 devices, which will be available in the UK from Mclennan Servo Supplies, will feature a low inertia copper foil rotor along with a rare earth neodymium magnet system. They will be offering a nominal torque of 35mNm, a starting torque rating of 400mNm, a nominal speed of 7700rpm and an acceleration response of 4ms.
Measuring 25mm in diameter, the motors will be available in either 12 or 24VDC. They are fit for applications where rapid start-stop, compact size and smooth speed performance are required.
Allied said that the DynaMax may also come with the optional OE22 2000ppr encoder –– a good match for high accuracy and high throughput positioning and robotics including electronic, semiconductor or medical equipment fabrication.
Encoder-less versions, which are efficient for precision pumps and valves, miniature actuators and specialised hand tools, are also available.
The motors are intended for long life operation, as their coreless design that provides zero motor cogging for speed regulation, high efficiency and low weight.
A range of planetary gearboxes yielding output torques to 4.5 Nm is also available for the series. Other options are custom winding and built-in spark suppression, customised shafts and mounting configuration, and alternative leads and connector interfacing.
