Product Description:

The BH-622-B-99-270 is a brushless servo motor manufactured by Kollmorgen for the Goldline B and BH Motors series. When paired with a 480 VAC drive, it supplies tightly regulated torque to indexing conveyors, pick-and-place heads, and similar motion axes found in automated assembly and material-handling cells. By integrating a rotor, stator, and position feedback device in a sealed housing, the unit serves as an electromechanical actuator that converts high-voltage three-phase power into precise rotary motion within closed-loop control systems.

Under steady operating conditions, the motor draws a continuous phase current of 8.43 Arms, enabling a continuous stall torque of 14.9 N·m when held motionless against load. For rapid acceleration, the drive can deliver up to 20 Arms, which lets the shaft reach a peak stall torque of 33.5 N·m for short intervals without thermal overrun. At its rated operating point, the motor delivers mechanical output of 4.4 kW while spinning at 4000 rpm; this operating pair sets the nominal speed-torque range used with gearheads, belts, or direct-drive couplings in high-speed production equipment. These electrical limits are intended for 480 VAC supplies, so the motor can be matched with properly sized inverters running the same bus voltage.

The motor’s phase-to-phase inductance of 32 mH moderates current rise time, allowing the control amplifier to issue high-bandwidth torque commands without excessive ripple. A rotor inertia of 0.00103 kg·m² balances dynamic response with load-coupling stability, making the device suitable for indexing cycles that demand both quick reversals and smooth settling. Position and velocity are reported through a resolver, and an embedded thermostat closes at 132 °C and opens again near 170 °C. Its normally closed contacts are rated for 4 A at 120 VAC, giving the drive a direct signal to reduce current if winding temperature exceeds safe limits.
