Multifunction Torque Testers


This single system covers all aspects of motor torque measurement, such as speed-torque, cogging torque, and torque ripple. Combined with a power meter, it can be used to measure induced voltage. May be used in combination with environmental testing equipment.

Primary Advantages

  • This model uses a simple structure with brake and various sensors configured on the main shaft for superior adherence at high speeds (up to 20,000 r/min).
  • Uses time-tested hysteresis braking for load control and a weight-gauge torque detector designed by Sugawara Laboratories for torque detection.
  • Allows easy core matching, with high precision using special motor-fixing hardware.
  • Offers superior motor fixing, thermal insulation, and bearing structure for use with environmental testing equipment.

Basic configuration

  • Torque measurement component: MTS-2N01
  • Control component: PC-MTS-01
  • Personal computer: Microsoft Window XP/7
  • Digital power meter: WT1800 (from Yokogawa Electric Corp.)
  • Environmental testing equipment: subject to separate consultation
