Three-Axis Torque Testers of Voice Coil Motors

PC-MCT5-15

Three-Axis Torque Testers of Voice Coil Motors

The PC-MCT-15 motor analyzer is a system for measuring the triaxial torque (Angle-Torque characteristics) of voice coil motors (VCM) used in various devices, including hard disk drives. The motor analyzer measures the torque vs. rotation angle by rotating the motor magnet (coil) at speeds ranging from 0.6 degrees/sec and 2.0 degrees/sec. Measurement results can be viewed on a computer screen and saved as CSV files.
