STEPPER MOTOR SM4247

SM4247 is a compact hybrid stepper motor. Unique balance of size and torque power makes this stepper motor an ideal solution for micromanipulators, positioners, grout feeders, semi-automatic machines of multi parameter control, sampling equipment, automatic analysers, mixers and devices for analysis of oil products.

To control SM4247 we recommend step motor driver SMD-1.8 or step motor controller SMSD-1.5.

The main parameters of stepper motor SM4247

  • Maximum holding torque: 4.4 kgf*cm (0.43 N*m)
  • Maximum current per phase: 1.68 A
  • Phase resistance: 1.65 Ohm
  • Phase inductance: 2.8 mH
  • Rotor inertia: 68 g*cm2
  • Weigh: 0.35 kg
  • Dimensions of stepper motor SM4247

    Motion accuracy of stepper motor SM4247

    The motor motion accuracy was tested with latest version of our stepmotor driver SMD-4.2. The examination was done in microstepping mode 1/256, during 2 full steps. The displacement error is below 0,03 degrees, that means less than 1,8 arc minutes. The test curve is below.
