Product Description:
Danaher manufactures the M062-FD09 with 88 Newton-centimeters of holding torque. Holding torque is the maximum static torque the motor can withstand without moving when powered. The high holding torque makes the motor useful in applications like robotic arms, CNC machinery and precision metrology systems that require positional stability during dwell or external disturbances.
The M062-FD09 has low rotor inertia of 0.24 kg-cm² which enhances its dynamic performance. Rotor inertia has a direct impact on how sensitive the motor is to acceleration and deceleration commands; lower values means lower moment of inertia which allows for faster angular velocity changes with less torque input. This enables motion control at high frequencies with less overshoot and power loss. In high throughput systems where fast indexing, real-time trajectory changes or short cycle times are required, the low inertia rotor design is critical. Automated optical inspection systems, semiconductor production and other high speed automation where accuracy and efficiency must coexist depend on this kind of dynamic reactivity.
The M062-FD09 is flexible in system integration as it is electrically compatible with both unipolar and bipolar drive topologies. It balances energy consumption and thermal performance in unipolar mode at 1.7 VDC and 4.7 A with 0.80 mH inductance and 0.35 Ohms winding resistance. In bipolar parallel configuration, it reduces winding resistance to 0.18 Ohms and increases current consumption to 6.7 A and reduces voltage to 1.2 VDC. This decrease in current consumption can result to higher torque at higher step rates. The motor can meet the mechanical precision requirements of demanding motion control applications with its 1.8° step angle and standard NEMA 23 frame which provides 200 steps per revolution and ±3% step accuracy.
