Product Description:
The SS451-1003 is a synchronous stepping motor manufactured by Danaher that operates on a single-phase 120 V source. Compatible frequency ranges include both 50 Hz and 60 Hz. When driving the shaft, the motor can choose between 72 RPM and 60 Hz.
The motor draws 0.8 A of electricity and has a horsepower of 0.025. The running force needs to be 450 oz-in for single-phase operation. At 50 Hz and 60 Hz, the motor can manage a load inertia of up to 5.5 lb-in when it is securely mounted. It has a 38 lb-in force capability at 60 Hz and a 9.1 lb-in capability at 50 Hz. A type of connection diagram known as B was utilized. Each winding has a current of 0.9 A and a DC voltage of 75 V. With one winding turned on, the minimum holding force is 550 oz-in. With two windings turned on, it is 700 oz-in. The usual amount of leftover torque is 25 oz-in. The motor weighs 14.3 lb, which is 6.5 kg, altogether. The SS451-1003 motor is made for accurate control tasks and works with NEMA 34D frame sizes. This motor is ideal for applications requiring continuous torque and speed, such as in factory automation. As long as the current and voltage values are met, the torque profile stays stable.
For the best operating life, these mechanical limits must be kept. The SS451-1003 synchronous stepping motor is capable of withstanding rotational forces of 25 lb and axial forces of 50 lb. The motor's specs make it good for systems that need to control motion and need constant power at different speeds. In motion control jobs, the set torque values for holding and running conditions make it possible to position things consistently and repeatedly.
Frequently Asked Questions about SS451-1003:
Q: Why do SS451-1003 windings draw 0.9 A current?
A: The 0.9 A per winding provides stable torque output. It ensures consistent motor performance under continuous and step-hold conditions.
Q: How does SS451-1003 maintain torque consistency?
A: Torque is maintained through specified holding and running torque values. These are achieved using controlled current and defined winding states.
Q: Why is SS451-1003 axial force rating important?
A: A 50 lb axial force rating ensures mechanical durability. It protects the motor shaft from axial load-induced failures during operation.
Q: Do SS451-1003 residual torque levels affect precision?
A: Yes, residual torque of 25 oz-in reduces backlash. This improves positioning accuracy and motion stability in precision systems.
Q: How does SS451-1003 handle load inertia variations?
A: The motor supports different load inertia with coupling types. This protects drive mechanisms and ensures stable motor dynamics under load changes.
