DMY Series
DMY Outer-Rotating Direct Drive Motor
- Type
- Outer-rotating direct drive
- Frames
- 3 (Ø110 - Ø280 mm)
- Continuous Torque
- 4 - 100 N·m
- Peak Torque (1 s)
- 12 - 300 N·m
The DMY turns the direct-drive family inside out: an outer-rotating torque motor where the load mounts to the rotating outer structure, so large pieces couple directly and inertia is optimized at the source. Fourteen models across three frames (Ø110 to Ø280 mm) span 4 to 100 N·m continuous and 12 to 300 N·m peak, with the high-resolution feedback system integrated in incremental or absolute form. It is built for high resolution, high torque and high precision applications, from glass-substrate wire cutting to laser machining.
DMS is the inner-rotating sibling for tight envelopes, 3.1 to 150 N·m on the same encoder stack. View DMS Series →

Models
The B suffix is the 20-bit absolute encoder, the 5 suffix the 3600-line incremental (4,320,000 sin/cos counts per revolution). Electrical specs are identical model for model across the two encoders; the Ø110 DMY4 frame is absolute only.

Encoder
Feedback is integrated; the encoder code decides drive compatibility.
- B 20-bit absolute — Works with the E1 drive only; ±5 arc-sec repeatability
- 5 3600-line incremental — 4,320,000 counts per revolution (sin/cos 1 Vpp), E1 or D1 drive; ±2.5 arc-sec repeatability
Accuracy compensation
Factory error mapping tightens angular accuracy.
- 0 Without compensation — ±30 arc-sec (DMY4 ABS), ±25 (DMY6/DMYA ABS), ±15 (incremental)
- 1 ±10 arc-sec — After error mapping
- 2 ±5 arc-sec — Tightest grade; the spec tables list it for incremental models
Axial/radial runout
- S 30/30 µm — Standard
- P 5/30 µm — Precision axial
- A 5/15 µm — Precision axial and radial
Sensors & protection
- P PTC temperature sensor — SNM100 in-winding over-temperature; without it, the E1 drive's overload detection guards the motor
- 0 IP40 — The only printed class; not suitable for corrosive gas, cutting oils or metal powders
Connector & cable
- S ABS scale standard — AMP joint with 0.3 m cable (wire length 1)
- A Optical scale standard — Intercontec M17 metallic joint, no cable (wire length 0)
