Product Description:

The TA51 V20 BP07 ER PT is a synchronous servo motor manufactured by KEB and included in the TA Synchronous Servo Motors series. It is built for closed-loop motion axes where accurate position, velocity, and torque control are needed in industrial automation cells, packaging machinery, and material-handling gantries. The unit converts electrical energy from matched drives into mechanical rotation through a 32 × 58 mm output shaft and monitors winding temperature with an integrated PT1000 sensor to protect the stator. Resolver feedback and temperature monitoring help the connected drive maintain stable motion control while supervising thermal load.

When operated on a 400 V bus, the motor draws a stall current of 5 A to hold its rotor motionless while producing a stall torque of 11.5 Nm. At rated load, it supplies a nominal torque of 10.8 Nm and reaches a nominal speed of 2000 rpm, which marks its continuous operating point. The voltage constant is 205.42 mV·min, indicating back EMF in relation to speed and supporting drive-side tuning for field-oriented control. A laminated steel flange sized 145 × 165 × 130 mm mates the housing to gearboxes or machine frames, and resolver feedback at 10 kHz with 7 VAC excitation maintains precise rotor angle information for the controller. Thermal endurance is supported by insulation rated for 155 °C, allowing elevated winding temperatures without dielectric breakdown. Brake power consumption is 24 W while the coil is energized.

Dynamic overloads are absorbed by a maximum torque of 34.5 Nm, giving extra headroom above the continuous region during acceleration and short peak demands. For safe stop functions, the integrated holding brake delivers 18 Nm of torque, is energized with 24 V DC, and releases in 50 ms. This brake action helps reduce waiting time between motion segments while keeping the shaft secure at standstill. The motor is suited to axes that must pause under load and then return quickly to commanded motion.
