Product Description:
The T840T-012 is a Servo Motor and it serves as an efficient tool and is considered ideal for industrial automation practices. The product is made by Sanyo Denki and it is classified under the series T SANMOTION Servo Motors.
The T840T-012 Servo Motor comes pre-wired with 1-meter lead wires which allows moderate installation flexibility without requiring immediate extension. It is able to resist a torque load of 12 N·m before it stalls which indicates its maximum torque under transient conditions. It is built to run continuously at 2500 RPM under rated load which represents its standard operating speed. It is well protected against solid objects larger than 1 mm and light water spray from angles up to 60° which makes it suitable for indoor environments with controlled exposure. It has a 0.0005 kg·m² rotor moment of inertia which indicates moderate resistance to speed change and is suitable for general purpose motion tasks. It has a 3.85 kg mass which reflects a compact medium size for its output class. It is featured with a shaft along with a keyway for secure mechanical coupling which prevents slip under torque load.
The T840T-012 servo motor delivers 0.4 kilowatts of continuous power which is adequate for low to medium demand applications. It does not have an oil seal which suggests it is not optimized for environments with significant oil or coolant exposure. The module electrical interface is provided through lead wires which allows basic point to point wiring without connectors. It comes with a built in tachometer which provides speed feedback and enables closed loop velocity control in servo systems. Without structural or thermal failure it can run up to 4000 RPM and gives a buffer for high speed applications.
Frequently Asked Questions about T840T-012:
Q: How does the IP43 rating benefit the T840T-012 Servo Motor in use?
A: IP43 offers basic protection against solid objects and angled water spray, making T840T-012 ideal for indoor automation. It ensures reduced risk of damage from minor environmental exposure.
Q: Why is a keyed output shaft used in T840T-012 Servo Motor?
A: The keyed shaft on T840T-012 ensures secure mechanical load transfer. It minimizes slip and misalignment during torque transmission under load.
Q: What are the advantages of the lead wire connection in T840T-012?
A: Lead wire connection on the T840T-012 simplifies integration in custom wiring setups. It offers flexible routing options compared to fixed connector types.
Q: What impact does 0.0005 kg·m² rotor inertia have on motor performance?
A: This rotor inertia enables stable motion control with reduced overshooting. It helps in achieving smoother acceleration and deceleration profiles in automation systems.
Q: Does the T840T-012 Servo Motor support encoder-based feedback systems?
A: No, the T840T-012 uses a tachometer for velocity feedback instead of an encoder. This is suitable for speed regulation rather than precise position tracking.
