摘要： An electric motor including: a first and second linear actuator, each linear actuator including a first and second coil respectively, a rotational shaft, a cam assembly mounted on the rotational shaft for translating linear movement of the two linear actuators to rotational movement of the rotational shaft, a controller programmed to generate during operation a first and second drive signal for first coil and second coil respectively, wherein the first drive signal causes the first linear actuator to generate a first torque on the rotational shaft that varies periodically over a complete rotation of the shaft and the second drive signal causes the second linear actuator to generate a second torque on the rotational shaft that varies periodically over a complete rotation of the shaft, and wherein the sum of the first and second torques produces a total torque that is substantially constant throughout the complete rotation of the shaft.
