R301-011E

Product Description:

The Sanyo Denki R301-011E fits into the Super DC Servo Motors family and was meant for setups where precision and compactness have to work side by side. The case comes in small, and the overall weight stays at 0.55 kg, leaving room in packed cabinets or slim frames for more hardware. Power is nothing to sneeze at, either, with a rated output of 39 Watts pushing just enough energy for step-and-repeat movements, conveyor tweaks, or smaller automation cells. Spin tops out at a rated revolving speed of 3000 min⁻¹, which fits well with faster lines or any equipment calling for steady but zippy motion.

Throw in the 72 V rated voltage and 0.11 N·m rated torque, and it’s pretty much deployment-ready for direct drive jobs or small actuators where accuracy outshines brute force. There’s a torque constant of 0.174 N·m/A, which helps keep each amp of current working as planned. Electrical control feels sharp because of the 0.26 ms electrical time constant, so incoming commands don’t wander or stall after signals reach the motor. Maximum stall torque gets a boost at 0.323 N·m, which comes in handy if something on the shaft sticks for just a second—no skipping beats or blowing fuses.

Everyone building gear for tricky installations checks for weight and smooth fitting. The 0.55 kg includes the encoder, so there’s no nasty surprises with door heights or bracket support. Heat rise stays manageable thanks to the efficient windings, and specialized setups allow the units to keep running even next to variable-frequency drives or PLCs. Most of these go to robotics, precision tools, compact assembly machines, or labs that don’t have the space for oversized gear.
