Product Description:
The T850-012 is a brushless servo motor developed by Sanyo Denki within the T SANMOTION Servo Motors series. Designed as a compact rotary actuator for positioning and speed-regulated tasks in industrial automation, it converts controlled electrical input into precise mechanical rotation suitable for pick-and-place heads, tool changers, and packaging axes. In motion systems, the unit pairs with a compatible servo amplifier to form a closed-loop drive, delivering feedback-guided torque to maintain commanded motion profiles under varying load conditions.
At its continuous operating point, the motor develops 2.16 N·m of stall torque while holding the shaft position without overheating. When supplied with the rated armature voltage of 80 V from the drive, it produces a mechanical output of 0.5 kW at a rated speed of 2500 rpm, supporting moderate-power applications such as indexing tables or feed rolls. The housing carries an IP43 protection rating, preventing the entry of solid objects larger than 1 mm and protecting the motor against water sprayed at angles up to 60 degrees from vertical. Power is delivered through 1000 mm lead wires that exit the stator, simplifying cabinet routing, while an integral keyed shaft transmits torque directly to couplings.
For transient moves, the drive can command up to 16.7 N·m of peak stall torque, allowing rapid acceleration without demagnetizing the rotor. Mechanical integration is aided by an 87.5 mm square flange that matches common IEC patterns, and the rotor inertia of 6.0 × 10⁻⁴ kg·m² balances quick response with load stability. The motor weighs 4 kg, reducing the load added to moving carriages during installation. The motor does not have an oil seal, so the front bearing area must remain free of cutting fluid and other liquids that could enter the housing. It also does not have a tachometer generator because speed and position control rely on feedback processed by the compatible servo amplifier.
