Provided is an electric motor comprising: a stator comprising stator poles arranged radially and a rotor comprising rotor poles, each comprising: a substrate comprising a magnetically permeable material and at least a first magnet and a second magnet. The magnets can comprise a respective proximal end proximal to the stator and a respective distal end opposite the respective proximal end, and distal from the stator. A distance between respective proximal ends of the magnets can be equal to or greater than a distance between respective distal ends of the magnets. Each rotor pole also comprise first and second proximal cavities, each cavity extending from the respective proximal end of a magnet for a given length along about the circumferential direction and away from the proximal end of the other magnet. Sum of the lengths of the proximal cavities can be about equal to a width of each stator pole.

Internal permanent magnet motor with an outer rotor

An electric motor, including a motor assembly having a rotor and a stator, and a switching assembly adapted to switch the motor assembly between a wye configuration, a delta configuration, and a neutral configuration. The switching assembly may include a plurality of actuators configured to move at least two movable contact members so as to select which configuration of the motor assembly is active.

Apparatus for switching between wye and delta configurations in an electric motor

An enclosure includes a housing defining an interior chamber for receiving an electronic assembly. The housing is made of a thermally conductive material so as to operate as a heat sink. The housing has a heat transfer surface within the interior chamber for receiving heat generating components thereon, and an interior groove within the interior chamber. The enclosure also includes a retaining clip having a clip length, a first portion extending along the clip length for engaging the interior groove, and a second portion extending along the clip length for engaging the heat generating components. The retaining clip is made from a resilient material and is sized and shaped such that positioning the first portion in the interior groove flexes the retaining clip and presses the second portion against the heat generating components so as to bias the heat generating components into thermal contact with the heat transfer surface.

Enclosure for an electronic assembly for a battery powered lawn mower

A vehicle such as a riding lawn mower may have at least one electric drive motor configured to drive at least one wheel, at least one electric blade motor configured to drive at least one cutting blade, and a battery module connected to the drive and blade motors. According to some embodiments, a method of controlling the vehicle may include: operating the blade motor according to a blade target speed; monitoring a blade current load for the blade motor; comparing the blade current load to a light load low threshold for the blade motor; and if the blade current load is less than the light load low threshold, decreasing the blade target speed.

Methods of controlling a lawn mower having electric drive and blade motors

According to one aspect, a vehicle control system. The control system includes a steering control coupled to at least one steerable wheel, the steering control having a first position, a second position and a plurality of positions therebetween. The control system also includes a steering sensor coupled to the steering control and configured to generate steering sensor signals based upon the position of the steering control. The control system also includes a control module coupled to the steering sensor, the control module configured to (i) record a first steering sensor signal value when the steering control is in the first position; (ii) record a second steering sensor signal value when the steering control is in the second position; and (iii) determine a current position of the steering control by comparing the first and second steering sensor signal values with a current steering sensor signal value.
