Servomotors for Industrial Automation and CNC Machinery

Servomotors are high-precision electric motors with built-in feedback for accurate position, speed, and torque control. They are used in CNC machines, packaging equipment, robotics, printing presses, and conveyor systems. Our catalogue features servomotors from Delta Electronics (ASDA-A2, ASDA-B2, and ASD-M series) and Veichi (SD600 and SD700 series) — ranging from compact 0.1 kW units to powerful 55 kW drives. A servomotor operates paired with a servo driver, and ready-to-use bundles are available as servo kits.

How to Choose a Servomotor

Key selection criteria include rated power, supply voltage, encoder resolution, and communication protocol with the controller. Below is a comparison of popular models based on actual sales:

ModelPower, kWSupplyEncoderProtocol
Delta ASD-M-0723-L0.73-ph/220V20-bitRS-232, RS-485
Delta ASDA-A2-1521-E1.51-ph/220V20-bitRS-232, RS-485, EtherCAT
Veichi SD700-7R6A-PA1.51-ph/220V17/23-bitPulse
Delta ASDA-B2-3023-B2.03-ph/220V17-bitRS-232, RS-485
Veichi SD600A-T3-3R03.03-ph/380V2500 PPRRS-485

For high-dynamics tasks (CNC, laser cutting), choose series with 20-bit or higher encoders and EtherCAT support. For simpler applications (conveyors, packaging machines), models with pulse control or RS-485 are sufficient.

Frequently Asked Questions

What is the difference between a servomotor and a servo driver?

A servomotor is an electric motor with a built-in encoder for feedback. A servo driver is the control unit that powers the motor and processes encoder signals. Both components are required for operation, or you can choose a ready-made servo kit.

Which servomotor is best for a CNC machine?

For CNC, we recommend the Delta ASDA-A2 series with a 20-bit encoder and EtherCAT support — providing positioning accuracy of up to 1,048,576 pulses per revolution. Power depends on axis load: typically 0.4–2.0 kW.

What encoder resolution is needed for precise positioning?

For standard tasks (conveyors, packaging) a 17-bit encoder (131,072 PPR) is sufficient. For CNC and laser equipment, a 20-bit (1,048,576 PPR) or 23-bit encoder is recommended for maximum motion smoothness.

Can a servomotor be connected to a single-phase 220V supply?

Yes, many series support single-phase 220V power — including Delta ASDA-A2 (suffix -E, -U), ASD-M, and Veichi SD600 (S2), SD700. Power on single-phase supply is typically limited to 3–7.5 kW.

Which communication protocol should I choose for a servomotor?

EtherCAT — for fast multi-axis CNC systems (cycle time from 250 us). RS-485/RS-232 — for simple single-axis tasks or PLC integration. CANopen — for distributed automation systems. Pulse — for controllers with pulse output.
