Lema - Linear Electro-Magnetic Actuator

LEMA series actuators were developed for attitude control of the 1U CubeSat skCUBE.

FEATURES price offer

Actuators are designed for the smallest possible coercivity Hc. Cores of the coils are made from modern amorphous materials with almost zero Hc and linear magnetization curve. Mechanical parameters can be adjusted for the maximal possible length with respect to the frame capacity of the CubeSat. The coil maximum control current is 200mA. The transfer curve of the actuator is linear in this range, which gives the actuator maximum energy efficiency.

Lema:

  • is made from components with extensive flight heritage on several space missions and complies with selected ECSS standards.
  • Flown hardware with successfull flight heritage
  • Best electromagnetic actuator on the nanosatellite market
