Servo Motor

A servo motor is a type of motor used in servo systems to control the operation of mechanical components; it is an auxiliary motor that serves as an indirect transmission device. It can precisely control speed, position, and torque according to commands and is widely used in the field of industrial automation.

In today’s increasingly demanding industrial environment, servo motors—key components of automation control—are capable of achieving precise control and rapid response. Even under varying load conditions and continuous production cycles, they can ensure safe, stable, and highly reliable operation.

In this issue, we’d like to introduce a relevant case study of TAKAHIRO Machinery.

 

Servo Motor Stator Assembly Line

Length × Width × Height: 16m × 3.5m × 1.8m

Process Flow

Incoming material—skeleton vibration feeder → skeleton pin insertion → pin insertion inspection (using camera vision detection) → wire winding/degreasing—tin plating on pin needles → resistor testing → skeleton insertion into sunflower assembly → thermal fitting of sunflower teeth and yoke → PCB assembly → automatic soldering of PCBs → visual inspection of soldering quality → performance testing → housing thermal fitting → stator depth pressing and inspection → housing coding → material discharge

 

Servo motor rotor assembly line

 

Length × Width × Height: 13 m × 2 m × 1.8 m

Process Flow

Rotor shaft & core tray feeding → Rotor shaft inserted into core → Brake gear fitted onto shaft → Rotor glue dispensing → Rotor magnetic steel insertion → Glue curing → Rotor assembly with front bearing → Rear bearing and end cap installation, with end cap glue dispensing → Rotor assembly with rear bearing end cap → Press-fitting of the rear cover with brake mechanism

 

Servo motor assembly line for fixed and assembled components

Length × Width × Height: 25 m × 2.5 m × 1.8 m

Process Flow

Stator component feeding → Stator assembly with wave washers → Rotor feeding → Rotor-stator assembly → Securing screws on the rear cover → Securing screws for the brake motor rotor-stator assembly → Welding wires and securing screws for the brake motor → Applying lubricant to the oil seal → Installing the oil seal → Mounting the encoder, locking the protective cover and rear cover, followed by calibration and zero-setting → Comprehensive performance testing → Motor dimensional accuracy testing → Motor running-in

 

1. High degree of line automation: This is a fully automated production line. At key workstations, precise sensors and imaging systems enable automatic inspection, automatic alarming, and automatic removal of defective products (NG materials). No manual intervention is required, significantly reducing labor costs.

2. High precision in the entire line operation: Fully takes into account protective mechanisms such as error-proofing, misplacement prevention, and interlocking of actions during the automation process. Real-time monitoring of equipment test data allows for early warning of trends in quality deviations, thereby enhancing the consistency of product performance and ensuring high yield in production.

3. High degree of line-wide informatization: We can customize a line-level MES system according to customer requirements, and based on product characteristics, implement in-process station scanning and code reading. This enables automatic binding of critical parameters during the assembly process, facilitating information traceability throughout the product’s entire lifecycle.
