Product Description:

The 802D4280-F08BK M motor is compact and heavy duty with torque steadiness and delicacy control. It has holding torque capability of 238 oz-in and value range of 178 to 252 oz-in, for dissimilar loads. The phase inductance value of the motor is 12.4 mH and resistance value is 3.12 Ohms, for easy electric response. It is laminated rotor with 0.0036 oz-in-s² rotor inertia for its deceleration and acceleration at a high speed.

It has 4.5 °C/W thermal resistance for its high capacity to dissipate heat away from it. It has parallel rated current per phase of 1.55 A DC. Handling is possible with 2.5 lbs (1.13 kg) weight even for high-quality performance. Designed with 3.38-inch square housing and NEMA 34 frame size, it has a heavy-duty type mounting style for stability under running conditions. It supports either 4-lead series or parallel type connections for simple mounting. There is an M2 encoder mounting feature to make it encoder-ready for high-accuracy feedback applications. The motor is encoded under M-class codes for compatibility in systems. It is more suited in applications requiring constant torque output and variable control settings. This is used in vibration-intensive and space-constrained installations. It is due to the rugged construction and compact size of this unit.

The excellent electrical efficiency and symmetrical torque range of the motor render it best suited for high-performance applications. The encoder feedback rate and mount flexibility increase its applicability. This motor is especially suited to give strong performance under a variety of operating conditions with electric as well as thermal efficiency. It is a perfect solution for automation applications, machinery, or servo where safe output with flexible connectivity and installation features are required.
