Product Description:
8MSA4M.E1-46 is a self-cooled synchronous servo motor. It is made by Kollmorgen for industrial applications. The motor requires 330 Volts input. Its nominal speed is 6000 RPM. The torque rating is 3 Nm, the power rating is 1.88 kilowatts, and the current rating is 4.25 Amps. The motor torque and current at standstill (zero RPM) are 5.3 Nm and 6.82 Amps. Maximum speed which the 8MSA4M.E1-46 motor can sustain is 12,000 RPM. The maximum value for motor torque is 21.2 Nm. The maximum value for motor current is 40.9 Amps. A holding brake is installed on this motor. Its voltage rating is 24 Volts DC and it delivers 11 Nm holding torque. Moment of inertia of the motor without the brake is 2.65 kg cm2. Weight of the motor without the brake is 5.6 kilograms.
The recommended cable cross section for B&R cables is 1.5 mm2. A 512-line multiturn encoder with EnDat interface is installed on the motor and provides feedback. With self-cooling, the maximum allowed temperature for the motor winding is 140 degrees Celsius. This maximum threshold is limited to 110 degrees by the connected Kollmorgen ACOPOS series drive. The mounting flange on the 8MSA4M.E1-46 motor complies with DIN 42948. A black polyurethane paint is applied to the surface of the motor hosing. During operation, the ambient temperature should be between -15 and 40 degrees Celsius. Above 40 degrees, the stall current and rated current derate by 10% for every additional 10 degree rise in ambient temperature. The ambient temperature must not exceed 55 degrees during operation. Above 1000 meters, the motor current and stall current derate by 10% for every 1000 meter altitude increase.
