Product Description:
The MT306B1-R2C2 servo motor is built by Kollmorgen as part of the MTC Servo Motors series. It is an AC synchronous unit intended for precision position and velocity control in automated pick-and-place heads, indexing stations, and light-duty packaging axes. The design translates drive current into proportional torque so that machine controllers can execute repeatable moves while keeping cycle times short and product quality consistent.
The motor draws a continuous line current of 5.35 A RMS, a value that sets the thermal loading limit for uninterrupted duty. At the rated shaft speed of 4600 rpm, copper losses are moderated by a winding inductance of 17 mH and a DC resistance of 1.94 Ω. The back EMF constant is 38.1 V RMS/krpm, which is compatible with 250 V RMS drives and helps protect the insulation from excessive voltage. During acceleration or transient load changes, the shaft can deliver up to 11.29 N·m of peak torque and withstand 22.2 A RMS of peak line current without demagnetizing the rotor. The stator has an 8-pole configuration and a torque constant of 0.630 N·m/A RMS, linking commanded current to mechanical output. Static friction of 0.052 N·m and a stall torque of 3.32 N·m at 40 °C indicate the current needed for smooth low-speed positioning.
Dynamic response is aided by a rotor inertia of 0.000111 kg·m², keeping servo-loop bandwidth high without sacrificing stability. Heat develops gradually because the thermal time constant is 31 min, allowing intermittent overloads within the permitted duty cycle. The electromagnetic stack supports a maximum acceleration of 101643 rad/s², allowing commanded speed changes to occur within controller update intervals. A rated mechanical output of 1.47 kW makes the motor suitable for medium-power axes that require efficient operation and fast throughput.
