KA840JXX

Product Description:

KA840JXX is a servo motor made by Sanyo Denki. The 0.4 kW rating, which specifies the motor's power output, is a crucial specification. This is how quickly a motor can drive a load and how much mechanical work it can do in a given length of time. The motor's efficiency and performance qualities are directly impacted by the armature voltage, which is rated at 85V. It also influences the electrical power needed. The motor will operate at its rated load at the 2500 min⁻¹ rated speed. This is crucial for situations where exact velocity control and a particular motion profile are needed. The motor's constant stall torque of 1.70 N·m also defines how well it performs under load. When the motor is stationary, it can maintain this torque forever without overheating. Applications that support loads or get rid of static friction need stall torque. The motor's greatest instantaneous torque is 12 N·m, which is the peak stall torque. For dynamic motion control and responsiveness, this high peak torque is essential for quick acceleration and deceleration.

The tachometer generator's rotor inertia of 0.12 × 10⁻⁴ kg·m² and the motor's 5.0 × 10⁻⁴ kg·m² rotor inertia are crucial for comprehending the dynamic behavior of the motor. Rotor inertia influences the motor's speed; a motor with less inertia accelerates and decelerates more quickly. A tachometer generator with its own rotor inertia enables exact speed feedback for precise motor speed control and monitoring. The retaining brake on the KA840JXX is crucial for both positioning accuracy and safety. This brake guarantees accurate placement in vertical or holding applications, stops unwanted motion, and automatically locks the motor shaft when power is cut off. To minimize slippage and ensure mechanical connections to driven components are secure, the output shaft is equipped with a key. The motor is resistant to environmental influences, as shown by its IP43 protection certification. This enables it to function in industrial settings by providing protection against solid items bigger than 1 mm and water sprays coming from any angle. For the motor to last and be dependable in a variety of settings, the operating temperature range of 0°C to 40°C specifies the acceptable temperature range for optimal performance.

For system integration, the motor's physical measurements—its 88 mm² flange and 4.64 kg weight—are crucial. To accommodate different mechanical interfaces, the motor's mounting dimensions are determined by the flange size. The motor's weight influences the system's dynamic performance, mechanical stability, total inertia and structural needs. These specifications are all made to perform well and dependably in industrial settings. Accurate feedback for closed-loop control is made possible by the tachometer generator. The shaft's keyway lessens the possibility of slippage and enhances the mechanical connection to the load, particularly at high torque levels.
