Product Detail
Introduce：
HAN’S Motor offer a high-performance, zero-maintenance servo solution. The DDR motor achieves extremely high torque density through its long diameter, short length and large number of magnetic poles. The DDR can be used as an indexing plate, providing programmable fast indexing that far exceeds the production capacity of traditional mechanical or variable reluctance technologies. It can also be used to replace mechanical transmission components, such as reduction boxes, synchronization belts, and rack and pinion reducers.
Advantages：
Direct drive, high dynamic response
High precision
Integrated BISS-C interface absolute position feedback
Inner rotor/outer rotor structure
High speed/low speed winding
Standard series products
Customizable development
