ThinGap’s New Line of Motor Kits Designed for Reaction Wheel Assemblies.
- High Efficiency: Using slotless, ironless coils made with fine stranded wire, the TGR series of motor kits lends itself to very low drag at high operating speeds, with a significant improvement over traditional iron core slotted motors.
- High Torque-to-weight ratio: ThinGap’s patented motor topology allows the TGR series to produce up to 12x the amount of torque available from competing motors of an equivalent size.
- Optimized Rotor Inertia: The motor kit maximizes the inertia for a given weight and size into the rotor. The resulting package is lighter weight for the same momentum storage capacity.
- Dynamic Response: The TGR series uses a wave-wound coil, which results in a back EMF that is sinusoidal, with a total harmonic distortion of less than 1%. When paired with a sinusoidal drive, torque ripple is minimized and much lower than similar motors.
- Scalable Design: The TGR series uses a highly scalable design, allowing for modifications to the envelope and output of the motor kits. Contact our Applications team for more details.
