This document introduces the features and characteristics of DYNASERV.
The catalog introduces the DYNASERV and LINEARSERV families of direct‑drive and linear motors. It explains the magnetic bias principle that gives a high torque‑weight ratio and describes the intelligent drivers that improve positioning speed and accuracy.
Detailed tables list the mechanical and electrical specifications for the DM1A, DM1B, DM1C, and related motor models, including torque, speed, encoder resolution, accuracy, and environmental limits. The document also contains selection guides, dimension drawings, and contact information for Yokogawa.
| Maximum torque (Nm) DM1A‑050 | 50 |
|---|---|
| Encoder resolution (pulses per rev) DM1A series | 4,096,000 |
| Weight (kg) DM1A‑050 | 14.5 |
| Rated velocity (rps) DM1A series | 1.0 |
| Insulating class | Class F |
It uses a magnetic bias method where a rare‑earth permanent magnet in the stator core generates a rotating torque proportional to the square of the sum of the magnetic fluxes.
The DM1A series uses an encoder with a resolution of 4,096,000 pulses per revolution.
The DM series can operate from –20 °C up to +46 °C (storage up to +86 °C).
