50mNms momentum wheel

Product introduction

  The 50mNms momentum wheel is for satellite attitude adjustment, with two types of structures, single-axis momentum wheel and three-axis integrated one, which can meet the demands of 6U~12U micro-nano-satellites. The product uses industrial-grade components under mass production mode, which is characterized by high cost-effectiveness, fast response, good consistency of data as well as high reliability.
