Atsense Resolver system measuring instrument RSM-100

Real-time measurement of angle and speed by branching resolver signal lines in a state-controlled motor systems.

It is now possible to branch resolver signals during driving control states to measure motor angle and speed. These signals can also be utilized as reference signals for various analyses.

Simultaneously measure and analyze the correlation with noise and vibrations.
Utilize for verification of control sequences and control mapping.
Enable in-depth benchmarking of driving control.

Features

• Branches resolver signals during control to simultaneously output ABZ pulses and analog signals proportional to angle and speed.
• Monitors and outputs excitation, sin, and cos signals.
• Supports resolver gear ratios from 1time to 20 times.
• Accommodates rotational speeds from 0 to 60,000 rpm.

Branch detection of resolver signals
Typical resolver signals are floating signals, so simply branching them with passive probes or clips may cause insufficient excitation current due to an increase in current paths, and noise inflow due to the GND connection of another device, etc. Thus, it will affect the signals and measurement of the existing measuring system and result in the impossibility of measurement.

This device with a high impedance detection section will make it possible to branch and measure resolver signals without affecting the existing system.
