TA2M V40 ER TW

TA2M V40 ER TW is a KEB motor in the TA Synchronous Servo Motors series. It operates at a nominal voltage of 400 V and has a nominal speed of 4,500 1/min for high-speed motion applications. The motor delivers 2.2 Nm of nominal torque during continuous rated operation and 2.4 Nm of stall torque at zero speed. Its maximum torque is 7.2 Nm for short-duration peak loads. The stall current is 2.15 A, while the maximum current is 6.4 A for peak operating demand.

The motor uses a BRX 2-pole resolver for rotor position and speed feedback. The resolver operates with a 7 VAC input at 10 kHz, supporting position measurement for servo control. A PTC thermistor monitors motor temperature by increasing resistance as the winding temperature rises.

The winding resistance is 18.504 Ω, which determines resistive electrical losses, and the winding inductance is 26.6 mH, which affects current response. Its voltage constant is 99.123 mV·min, relating generated voltage to rotational speed. The rotor inertia is 0.66 kgcm², which affects acceleration and deceleration response. The motor weighs 2.9 kg.
