So you're looking at a small servo motor that runs at 3000 rpm on 220V AC, and honestly these 40SE models are pretty much the go-to for compact precision work — we've sold them for years to folks who need something that fits in a tight space but still delivers consistent torque, the 0.05kW and 0.1kW versions being the two main options depending on whether you need lighter or slightly heavier load handling.
The body length runs 93.5mm for the smaller one and 104.5mm for the larger, but if you add the brake option that jumps to 123.5mm or 134.5mm, and you'll want to factor that into your mounting layout because it's not always obvious until you're bolting it in. Rated torque sits at 0.16N.m and 0.32N.m respectively, with maximum torque about three times that — 0.48N.m and 0.96N.m — which is better than some comparable units we've seen form other suppliers. The rotor inertia is really low at 0.025 and 0.034 x10⁻⁴ kg·m², and that's what gives it the snappy response for positioning tasks.
What it does is handle those applications where you need smooth motion at low speeds — think pick-and-place machines, small conveyor drives, or even some lab automation gear — and the F class insulation means it can run hotter than standard without degrading. One thing it's not great for is heavy continuous load at max torque for extended periods; it's really designed for intermittent duty cycles where that overload capacity shines. Most buyers go with the incremental encoder for general use, but the absolute encoder is there if you need position retention after power loss, and resolver is an option if you're in a high-vibration enviornment.
The photoelectric encoder option gives you clean feedback signals, and we typically see these motors paired with drives that handle variable frequency starting — that's the standerd method here. Protection rating is IP54, so it's dust-resistant and handles splashes, but don't submerge it. The back EMF constant runs about 34.3V per krpm on the smaller model and 30.8V on the larger, which matters when you're matching it to a drive's voltage limits — something we've seen buyers overlook and then have to swap components.
Anyway, ordering usually means picking your model number — 40SE50530 for the 0.05kW or 40SE51030 for the 0.1kW — and specifying encoder type upfront because that changes lead time by maybe 20 days or so. We always recommend checking the torque constant, which is 0.27N.m/A for the smaller and 0.32N.m/A for the larger, against your load calculations; it's a simple number but it saves headaches later. MOQ is typically 10 units for stock items, but we can do smaller quantities if you're prototyping.
The 40SE50530 is rated at 0.05kW with 0.16N.m torque, while the 40SE51030 is 0.1kW with 0.32N.m torque. The body length also differs: 93.5mm for the 40SE50530 and 104.5mm for the 40SE51030.
Our standard MOQ is 10 units per model, but we can discuss smaller quantities for sample orders or trials. Just let us know your needs.
You can choose between incremental or absolute encoders, and we also offer a resolver option if needed. Just specify which one you want when ordering.
Yes, we provide ISO9001 certification along with test reports that verify the F class insulation rating. All quality docs are included with each shipment.
