## Abstract

A mount for an electric motor, the mount comprising a sleeve for receiving a motor, the sleeve having a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of plurality of projections and the plurality of projections extend along the longitudinal axis. The sleeve may receive the motor via the first end or the second end. The plurality of projections may be spaced around a circumference of the sleeve. The plurality of projections may comprise a pattern of substantially constant frequency around the sleeve. The plurality of projections may be substantially V-shaped with the point extending along the longitudinal axis from the first end of the sleeve.

## Claims

### Claim 1

A motor mount, the mount comprising a sleeve for receiving a motor, the sleeve comprising a longitudinal axis extending between a first end and a second end, wherein the first end comprises a plurality of projections and the plurality of projections project from the first end of the sleeve along the longitudinal axis.

### Claim 2 (depends on 1)

The mount of claim 1, wherein the sleeve receives the motor via the first end or the second end.

### Claim 3 (depends on 1)

The mount of claim 1, wherein the plurality of projections are spaced around a circumference of the sleeve.

### Claim 4 (depends on 1)

The mount of claim 1, wherein the plurality of projections comprises a pattern of constant frequency around the sleeve.

### Claim 5 (depends on 1)

The mount of claim 1, wherein the plurality of projections are substantially V-shaped with a point extending along the longitudinal axis from the first end of the sleeve.

### Claim 6 (depends on 1)

The mount for a motor of claim 1, wherein a radial seal is provided and the radial seal extends around a circumference of the sleeve.

### Claim 7 (depends on 6)

The mount of claim 6, wherein the radial seal is a lip seal.

### Claim 8 (depends on 6)
