Product Description:

The R850-012EL0 is a 500-watt servo motor by Sanyo Denki. It is a highly efficient servo motor with high performance and durability. The rated torque of this motor is 1.96 Nm. It operates at up to 4000 rpm, so it may be used in machines that have to work accurately at high speed. The R850-012EL0 has a weight of 4.0 kg, which makes it compact and easier to place in automated processes such as robotics, CNC machines and conveyors. It has thermal resistance of 1.0 K/W and a thermal time constant of 40 minutes, which provides stability of performance over the long run.

The Stall Armature Current is one of the main characteristics of this servo motor, and it has a 7.6 A stall current. It represents the maximum current that the motor can carry without rotating and with full load. It is important that when the motor starts or is driven to stop by external force, the current provides the required torque to start the rotations without overheating the motor. This feature makes the startup safe even with heavy loads, and low-speed relays are installed to protect the motor in the case of harsh operating conditions.

The Maximum Rotating Speed of 4000 rpm is another significant feature. This is the revolutions per minute which can be achieved by the motor shaft in no-load conditions. The motor is suitable for high-speed applications, as it operates at a higher RPM, which enhances its overall productivity. This servo motor can deal with high torque tasks as well as fast movements easily because of its instantaneous maximum torque, which is 12.0 Nm.
