Product Description:

The R406-081EB7 is a compact and efficient DC servo motor from Sanyo Denki's Super DC Servo Motors series, designed for precise motion control in lightweight automation systems. With a rated output of 60 watts, it can be used where fine control and responsiveness are required, i.e. in lab equipment, medical or miniature robotic systems. This motor has a nominal armature voltage of 75V and has a rated rotating speed of 3000 rpm with a maximum speed of 5000 rpm.

The R406-081EB7 with a continuous stall torque of 0.24 Nxm and a peak torque of 1.8 Nxm can provide bursts of high torque and is also stable during continuous operations. Its high efficiency in the conversion of electrical energy to mechanical energy is evident in a torque constant of 0.183 Nxm/A and a rated armature current of 1.2 A. It is also capable of providing a stall armature current of 1.3 A and a maximum instantaneous armature current of 10 A, and has the ability to support fast dynamic operations while supporting motor integrity.

The motor offers reliable thermal performance, with a thermal resistance of 2.8?K/W and a thermal time constant of 20 minutes, ensuring a gradual temperature rise during operation and efficient heat dissipation. It is highly compatible with the DA2D020 servo amplifier and ensures precise motion control and high-quality performance. The armature winding resistance (11.7 ohms) and inductance (5 mH) help maintain consistent current flow and contribute to a low rate of voltage variation, thus ensuring stable motor performance. The R406-081EB7, in general, is one of the highly accurate, stable and thermally efficient tools to provide compact motion control systems under harsh industrial conditions.
