Description

This machine is a BLDC (PMSM) permanent magnet motor with pure sine wave BackEMF. The slotless construction exhibits continuous stall torque with zero cogging and zero detente torque. The standard winding topology is a 3-Phase Y. Optional windings provide a broad range of input voltages and speed/torque variations. An encoder for conventional 3-phase electronic commutation is integrated. All polymer based parts are 3D printed.
