DEVELOPMENT AND EVALUATION OF LINEAR MOTORS

Measuring the performance of a linear motor (with an operating rate of less than one cycle per second) is traditionally a cumbersome process that requires a power meter, a digital oscilloscope, and a manual table of values:

  1. Use a digital oscilloscope to measure speed and torque mechanical output
  2. Use a power meter to measure values of torque at specific speeds
  3. Create a T-N(Torque-speed) characteristics table from above data
This process is much simpler using a PZ4000 to perform all three of these functions.
  1. Analog out put -- F/V-converted pulse signals from digitized encoder embedded in the motor driver.
  2. Torque signals (analog output) from an accelerometer mounted on the linear motor driver.
  3. Three-phase PWM waveform from the driver

Solutions
Performance required from power meter
  • Synchronized measurement of motor rotation, torque and power from motor driver
  • High-speed sampling to achieve sufficient time resolution in a short period of time
  • Noise-resistance and high repeatability
Benefits for the user
  • The measurement value is reliable because it calculates power parameters synchronized with the acquired waveform data.
  • Simultaneous measurement of impressed power and mechanical output is available by using a power input module and a sensor input module. The PZ4000 can easily perform a total evaluation of the motor.
