CN-400BT-10A4

Product Description:

The CN-400BT-10A4 motor slotting into Sanyo Denki’s Super DC Servo Motors stands out thanks to a straightforward but powerful build. Right from the spec sheet, there’s that rated output of 110 W, matched up with a steady rated torque of 0.34 N·m that helps cuts through typical loads faced on a busy automation line. The maximum rotating speed lands at 5000 rpm, making it good for setups that need snappy, precise response every time. With a rated armature voltage set at 75 V, this motor adapts easily to a range of industrial drives, and the rated armature current of 2 A helps keep use predictable.

Size-wise, nothing overcomplicated here, just a compact bit of machinery shaped for best fit in automation benches and equipment frames where room runs out fast. The continuous stall torque sits at 0.42 N·m, so it won’t drop off when workloads get stuck and push back. Instant torque climbs to 3.4 N·m for those rough, split-second acceleration jumps demanded by high-cycle applications. Stall current at 2.1 A and an instantaneous maximum armature current measure at 18 A, meaning the windings have some breathing room when things get heated up, but thermal resistance listed as 2.4 K/W means cooling needs some thought on longer cycles. That friction torque of 0.022 N·m makes movement smoother—less shaking, fewer surprises during starts or stops.

A thermal time constant of 20 min lets heat spread out slowly, so the servo is less likely to see temperature panic unless something really goes wrong. Armature winding resistance at 4.8 Ω means quick feedback, especially in tighter closed-loop programs found in newer automation software. The package stays stable because the design makes torque delivery even across bursts or reversals.
