UNITED MOTION INC. Performs Pre-Shipment Encoder Signal Inspection to Ensure Reliable Motor Feedback
At UNITED MOTION INC., every motor with an encoder goes through a dedicated inspection process before shipment. Recently, our quality control team completed encoder waveform testing on a batch of motors to verify the stability and consistency of their feedback signals.
Encoder Signal Testing Before Delivery
The encoder is an important feedback component in a motor control system. It provides information such as rotational position, speed, and direction to the controller. Stable encoder signals are essential for accurate motion control.
As part of our pre-shipment inspection, the motors are connected to a digital oscilloscope to monitor their encoder output signals. Engineers examine the waveform displayed on the oscilloscope and check whether the signals meet the required specifications.
The inspection focuses on key parameters such as:
- Encoder signal stability
- Signal amplitude
- Pulse consistency
- Phase relationship between output channels
- Signal noise and distortion
- Rotation direction feedback
The waveform shown during testing provides engineers with a direct view of the encoder’s electrical output, allowing potential signal abnormalities to be identified before the motors are delivered to customers.
An Additional Quality Check for Motion Control Applications
Encoder-equipped motors are commonly used in applications where controlled speed, positioning, or feedback is required, including industrial automation, robotics, AGVs, material handling equipment, and other motion control systems.
By performing waveform testing before shipment, UNITED MOTION INC. adds an additional inspection step to the motor quality control process. This helps ensure that the motor and encoder work together properly before entering the customer’s system.
For B2B customers, consistent quality and reliable feedback performance are important factors when integrating motors into automated equipment. Our pre-shipment testing process is designed to provide customers with greater confidence in the motors they receive.
Quality Control from Production to Shipment
At UNITED MOTION INC., quality inspection is an integral part of our motor manufacturing process. From electrical testing to encoder signal verification, each inspection step helps us maintain consistent product quality and support the reliability requirements of our customers.
