Product Description:

The GAM1A4005F0CRK1 is a compact rotary motor produced by Sanyo Denki for the G SANMOTION AC Servo Motors series. Designed for industrial automation, it converts inverter output into tightly controlled shaft rotation for light conveyors, semiconductor handlers, and inspection stages. The motor integrates a batteryless absolute encoder, so controllers receive valid position data immediately after power-up. Its brake winding draws only 0.26 A to hold the shaft in position during emergency stops or extended shutdowns.

Under dynamic demand, the motor can reach a maximum speed of 6500 rpm, allowing short acceleration bursts well above continuous operating levels. During these bursts, it resists the load with a peak stall torque of 0.56 N·m while drawing up to 2.9 Arms from the drive. The motor has a torque constant of 0.244 N·m/Arms, linking commanded phase current to delivered torque for feed-forward control. All windings have a 100 VAC insulation class, so the unit can be paired with low-voltage servo amplifiers commonly used in compact equipment. This electrical arrangement supports responsive torque control during rapid changes in speed or load.

Continuous operation is rated at 3000 rpm, where the shaft supplies 0.159 N·m with a steady phase current of 0.81 Arms. The mounting interface uses a 40 mm square flange, and a round, keyless shaft simplifies connection to fine-pitch pulleys and compact couplings. An internal resistance of 7.0 Ω balances thermal rise with servo response, while an oil seal prevents lubricant from reaching the encoder cavity. Base stall torque is 0.167 N·m at the same 0.81 Arms current, providing predictable holding behavior during dwell periods. The absolute encoder retains position information without a battery, eliminating periodic battery replacement in high-cycle machinery. This feedback arrangement also allows the control system to recover position data immediately after an interruption in power.
