permanent magnet electric servo motor
Lightweight and compact – short body length, minimal footprint.
High torque – up to 3× overload capability.
High speed – smooth operation up to 6,000 rpm.
Excellent stability and low cogging torque – enabled by a new electromagnetic design with a 10‑pole/12‑slot configuration.
High protection and long service life – stator coils are integrally potted (encapsulated).
Versatile compatibility – supports incremental and absolute magnetic encoders.
Cost‑effective – high power density for the price.
Rated voltage (D Series): 220 V – 380 V;waterproof servo motor;high power servo motor
Typical applications: collaborative robots and heavy‑load six‑axis robots;servo motor for robotic arm

| Note: All eight models with a 60 mm flange (four power ratings, each available with or without a brake) share the same shaft extension, key/keyway, and flange pilot dimensions. Shaft diameter S = ⌀14 +0.005/-0.015; flange pilot diameter FS = ⌀50 +0.010/-0.025; key dimensions: LS = 11, Q = 5, QL = 25, and QH = 16.8. In the "Brake" column, "No" indicates a motor without a brake, while "Yes" indicates a motor equipped with a brake. | |||||||||||||
The above dimensions are standard mounting sizes. Alterations can be made to meet specific customer requirements.
Important: Never apply impact or shock to the motor shaft – doing so can cause irreversible damage to the encoder at the rear end of the shaft.
