MicroMo announces a new version of our powerful 4490 Brushless Motor. The dimensions remained unchanged: 44 mm diameter x 90 mm. The combination of skew-wound (System FAULHABER) and high-performance neodymium magnet (NdFeB) was maintained. The crucial detail lies in the way the three-part windings of the coil are wired.
Brushless DC-Servomotors
In the 4490 ... B series, the windings are delta-connected. This results in higher motor currents together with lower voltages. These motors are particularly suitable for high-speed applications.
Conversely, the prominent feature of the new 4490 ... BS is its high torque. The partwindings are star-connected. The motor currents are therefore lower, while the voltage is higher.
Precision gearheads
Even more torque is achieved by combining with a 44/1 series planetary gearhead: 16 Nm for continuous operation and as much as 20 Nm for intermittent operation.
Encoders
The optical encoder, Series 40B with protection classification IP 54, can be mounted to the motor and the overall length extends only 44,3 mm. As a result, they open up entirely new possibilities in applications imposing particularly stringent standards on the positioning, measurement and control accuracy of speed.
Drive electronics
The FAULHABER Group offers various motion control possibilities for this drive unit, suitable for a wide range of requirements such as, for example, performing a wide variety of speed profiles, reverse operation, start/stop and stand-alone positioning modes.
