LS Series Brushless Motor




Our standard products are the LS-Series and TG-Series motors that include various high performance brushless permanent magnet machines designed with a common stator and mount architecture. Different rotor options result in varying torque capacities. This allows optimization of weight and efficiency based on application torque requirements. Various stator windings enable a range of operating voltages. Performance and mechanical parameters of the rotor options are summarized here. Click on the individual data sheets for details on performance and winding options. All models can be run as motors or generators. Contact ThinGap for further details.
