Product Description:
The P50B05020DCL61 servo motor is manufactured by Sanyo Denki as part of the P5 Super BL Servo Motors series. This brushless DC unit is intended for positioning and velocity control in automated pick-and-place stations, small actuators, and indexing tables. Its closed-loop operation supports repeatable rotary motion when paired with a compatible servo drive and feedback system.
This model delivers a continuous stall torque of 0.686 N·m, allowing it to hold a load without movement while the commanded current is sustained. Under rated excitation, it turns at 3000 rpm, a speed suited to compact machinery with responsive servo control. Shaft power reaches 200 W, allowing the motor to drive light mechanical transmissions without external gearing. A permanent-magnet brake supplies 0.353 N·m of holding torque and engages automatically when power is lost, securing vertical axes during shutdown. Mounting follows an IEC square flange pattern with a face size of 54 mm, simplifying installation with compatible equipment in the same frame class.
For transient motion, the rotor can withstand a peak stall torque of 1.96 N·m when the drive supplies up to 5.5 Arms of phase current. Current rise is governed by an electrical time constant of 2.9 ms, while speed changes follow a mechanical time constant of 0.9 ms for a quick response to command changes. The winding produces 0.436 N·m per Arms, allowing the control system to calculate torque from measured current. Phase resistance is 3.4 Ω, and the rated armature current is 1.6 Arms; both values should be considered when selecting the drive and evaluating thermal performance. During temporary overspeed operation, the rotor can reach 4500 rpm. A 24 V coil draws 0.4 A to release the brake, permitting normal shaft rotation while control power is available.
