Product Description:
The 8MSA3M.E1-42 Synchronous Motor includes robust protection, efficient cooling and advanced control modes features. The module is linked with the 8MS Three Phase Synchronous Motors series. B & R Automation which is a leading automation solutions provider have built this synchronous motor.
The 8MSA3M.E1-42 motor continuous mechanical power output capability is 0.63 k watts which it can deliver under normal conditions. It has a 1.69 ms of electrical time constant value which affects dynamic response. The module has 12.7 ohm of resistance of the stator winding per phase which can lead to greater heat generation and energy losses. To safely carry rated current without excessive heating or voltage drop the recommended wire thickness is 1.5 mm². During starting it can generate 1.3 newton meters of torque under load. To operate with this motor the optimized servo drive compatible with this model is 1016. This synchronous motor has a torque constant value of 0.78 newton meters per ampere. The integrated brake when engaged can hold 2.25 4 nm of torque which prevents the motor from turning when unpowered. Excluding any braking mechanism it has 2.25 kg of total mass.
The 8MSA3M.E1-42 motor can output 1 nm of continuous torque effectively. The inductance of each stator phase is 21.5 mega hertz which affects electrical dynamics and filtering requirements. Due to its braking its moment of inertia is 0.18 kgcm² which increases the total mass and impacts acceleration. For overcoming short term load spikes it can produce 5.2 amperes of peak torque. Under full voltage when the rotor is not rotating it can draw 1.67 amperes current.
